Signals and pthreaded applications are a poor match. OpenAFS has had the softsig system (currently in src/util/softsig.c) in an attempt to alleviate some of these problems. However, that implementation itself has a number of problems. It uses signal functions that are unsafe in pthreaded applications, and uses pthread_kill within its signal handlers. Over the years it has been responsible for a number of portability bugs. The old implementation continues to receive signals in the main thread of the application. However, the handler code is run within a seperate signal handler thread. When the main thread receives a signal a stub handler is invoked, which simply pthread_kill()s the signal handler thread. The new implementation simplifies things by only receiving signals in the handler thread. It uses only pthread-compatible signal functions, and invokes no code from within async signal handlers. A complete test suite is supplied.
