As runScript, but runs the commands in parallel.
If useThreads=false (default), the script will be run in an empty environment (same as running a new omc process) with default config flags.
If useThreads=true (experimental), the scripts will run in parallel in the same address space and with the same environment (which will not be updated).
function runScriptParallel input String scripts[:]; input Integer numThreads = numProcessors(); input Boolean useThreads = false; output Boolean results[:]; end runScriptParallel;
