 We really shouldn't be doing a whole lot in our signal handler.  The
 signal handler can get called in the middle of a malloc, for example,
 and if the signal handler tries to allocate memory then the program
 can deadlock.

 This change works around that problem by having the signal handler
 write to a pipe.  Our main program watches the pipe for incoming data
 and performs the appropriate action.

 This patch is from Shaun Lindsay at Meebo.

 Fixes #10324
