You cannot run arbitrary code from a signal handler. The sigaction man page has a list of what library functions *can* be called from a signal handler. *Everything* else is off-limits, including all of Cocoa and all of the Objective-C runtime. You were doing it wrong, now you're doing it right, and your problem went away. Seems like no surprise there!
