Thank you Bob Byrnes for this info and analysis. Perhaps it will result in a solution to a long simmering problem. I use cygwin VERY aggressively. A cron job launches a 20,000 line perl script (not including CPAN modules by other authors) that does complex network automation tasks via multiple chained telnets and ftps. (Eventually to use ssh). Cron launches this script every five minutes and multiple instances share resources managed by semaphores. cgf wasn't even remotely in the mood for endorsing cygwin for this kind of 'abuse' (not his exact words). Nevertheless, for "the most part" it works extraordinarily well. My biggest headache is - occasional DEADLOCKS. About once or twice a day a bash process attempting to start an ftp instance will hang - and freeze everything clear up to the perl parent process that launched it. Perl itself even hangs and stops writing output to log files and the terminal. The deadlock situation will last indefinitely until I do a kill -9 and terminate the last bash shell launched by the perl script. Then, every other process associated with the parent perl script "comes back to life". I am not a c/c++ programmer. My expertise is in Perl - and there it shall remain. I spent a couple hours a few weeks ago trying to incorporate strace into the mix I run, but it turned out to be a really complicated undertaking - so I gave up on it. So I apologize for effectively offering nothing more than a BIG "me too!!". That said .....
