## Main asynchronous execution function
## This function can monitor given pids as background processes, and stop them if max execution time is reached. Suitable for multiple synchronous processes.
## It can also take a list of commands to execute in parallel, and stop them if max execution time is reached.
## Function has 8 execution modes
# WaitForTaskCompletion mode: Monitor given pids as background processes, stop them if max execution time is reached. Suitaable for multiple synhronous processes.
# 1 : WaitForTaskCompletion, semi-colon separated list of pids to monitor
# 2 : WaitForTaskCompletion, list of pids to monior, from file, one per line
# Example of improved wait $! emulation
# ExecTasks "some_identifier" 0 0 0 0 1 1800 true false true true 1 $!
# Example: monitor two sleep processes, warn if execution time is higher than 10 seconds, stop after 20 seconds
# sleep 15 &
# pid=$!
# sleep 20 &
# pid2=$!
# ExecTasks "some_identifier" 0 0 10 20 1 1800 true true false false 1 "$pid;$pid2"
# ParallelExecMode: Take list of commands to execute in parallel, stop them if max execution time is reached.
# Also take optional conditional arguments to verifiy before execution main commands. Conditional command exit code 0 means ready to execute. Other exit codes will ignore/postpone main command.
# 3 : ParallelExec, semi-colon separated list of commands to execute in parallel, no conditions
# 4 : ParallelExec, semi-colon separated list of commands to execute in parallel , semi-colon separated list of conditional commands, ignoring main commands on condition failures
# 5 : ParallelExec, semi-colon separated list of commands, semi-colon separated list of conditional commands, postponing main commands on condition failures
# 6 : ParallelExec, list of commands from file, one per line, no conditions
# 7 : ParallelExec, list of commands from file, one per line, list of conditional commands from file, one per line, ignoring main commands on condition failures
# 8 : ParallelExec, list of commands from file, one per line, list of conditional commands from file, one per line, postponing main commands on condition failures
# Exmaple: execute four du commands, only if directories exist, warn if execution takes more than 300 seconds, stop if takes longer than 900 seconds. Execute max 3 commands in parallel.
# commands="du -csh /var;du -csh /etc;du -csh /home;du -csh /usr"
# conditions="[ -d /var ];[ -d /etc ];[ -d /home];[ -d /usr]"
# ExecTasks "some_identifier" 0 0 300 900 1 1800 true true false false 4 "$commands" "$conditions" 3
# ParallelExecMode also creates output for commands in "$RUN_DIR/$PROGRAM.ExecTasks.$id.$SCRIPT_PID.$TSTAMP"
