- Completed Multithreading of POSIX_SIG_Proactor.
- Introduced another constructor for ACE_POSIX_SIG_Proactor for taking
signal mask to be used with the Proactor.
- Thanks to Dave Butenhof <butenhof@zko.dec.com> for helping a lot to
understand the various things in the POSIX4 standard.
- Thanks to Dave suggestion of keeping null_handler for the sigaction
to real-time signals. With this and a couple of other correct POSIX
things SIG proactor is now working with in Solaris 2.7.
- Lynx OS doesnt support <pthread_sigmask>, so it couldnt be
multithreaded. Enabled AIOCB_Proactor for this platform.
- Added an example to make use of the real-time signal numbers for the
asynchronous I/O calls.
