[Israel.pm] Parallel jobs

I need them basically to run (more or less unrelated ) tasks in parallel.  For example: Connect to dozens of stations and run there a long operation.  I don't want to wait long time by doing them sequentially.

I prefer threads, but I wrote in the original mail why I can't.
