Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Signal.cpp: There was a major portability violation in the + ACE_Sig_Handler::dispatch() method, which was previously + acquiring a mutex lock. This is NOT permitted in the POSIX + signal handler spec. In addition, the implementation had other + nasty consequences related to dynamic allocation of memory in + the signal handler, which has a bad habit of breaking + non-reentrant uses of "new". The consequence of all this is + that you really shouldn't be modifying signal handlers via the + Reactor in multiple threads of control. In general, threads and + signals are just plain evil, so they are best addressed via + sigwait() anyhow... + + Thanks to Sumedh and Naga for first tracking this down. + Thu Apr 16 20:51:42 1998 David L.
