*BREAK-ON-SIGNALS* is better than what Hunchentoot previously had - You're sent to a the debugger, making actual analysis possible, and the technique works everywhere, not just in Hunchentoot.
Is it? For example USOCKET attempts to parse a string that might or might not be an integer in its host resolution mechanism and catches the signal. *BREAK-ON-SIGNALS* always jumps in there which is pretty annoying and gets in my way.
One could argue that this particular issue is misbehaviour in USOCKET but then again it's very common to catch signals routinely too.
