IMO, Windows and *nix/POSIX IPC are just too different to successfully wrap them over in a common interface. I've not found a single 'portable' module that works well on Windows.
in reply to Re^3: What is the preferred cross-platform IPC module?
in thread What is the preferred cross-platform IPC module?
I disagree. C Std Lib pulls it off. Interix and Cygwin pull it off. Signals on Windows are called Alertable IO. "Safe" signals on Win32 Perl are Windows Messages on the message queue, non-safe signals (CRT Ctrl C and exit) usually will crash the perl interp since they actually run from another thread. On the other land, if you what you mean by "common interface" means "compile and go api compatibility", then no. Regarding POSIX-ish modules working on windows, unless they wrap an external library which already does windows, I agree, there are very few outside the Win32::* namespace that have windows specific code.
