This came about as a way to avoid having to grep through the entire source code to find unused signals when I was looking for a free signal to use to control hardware virtualization. I accidentally used both SIGTMR (it's not exactly obvious that/why we have a 1s timer ticking in the background) and SIGUSR1 before grepping for all calls that install signal handlers. I agree that the usefulness of this is currently somewhat limited since most of the signals have a well defined meaning (SIGTERM, SIGABT, SIGFPE, etc.). However, it will become more useful as we start to use other signals (e.g., for hardware virtualization). - Andreas ----------------------------------------------------------- This is an automatically generated e-mail.
