Thanks to Ken, Joel and drieux for the suggestions. I take if from your responses that Perl doesn't automatically restart system calls after a signal is processed as Programming Perl and the Perl Cookbook suggest it does. I don't actually own the code that is doing the read, so its not easy for me to modify it. This is happening within my Perl debugger code. It could be any blocking system call (read/write/flock/select, etc.). I use a signal to get my debugger's attention so that I can set/clear a breakpoint or whatever while the client script is otherwise occupied. From the user script's perspective, I want it to appear as if the signal never happened.
