Log Message:
Fix a problem reported by Michael Hitch.  Basically, our libc relies on the
non-standard way of invoking sigreturn, specifically a side-effect that I
overlooked.  Thus, longjmp's return value was getting clobbered.

Sigh, so burn trap #3 just as sigreturn.

XXX We need an SVR4-style {get,set}context(2) to avoid wasting new
XXX trap vectors in the future.
