In message <20040512082626.14FB723410@thoreau.thistledown.com.au>, you write: 

-> Yay for me :-(  Do any of the regression tests regress/lib/libc/*setjmp*
-> able to reproduce the panic, and if so is it easy to backtrack the kernel
-> to find out when that end of the problem first started occurring?

Sadly, no. I haven't ran all of regress (yet) but all the *setjmp* tests
worked as did the sigtramp etc. :-<

Maybe interestingly, regress/lib/libpthread/siglongjmp1 fails with:

	./siglongjmp1
	siglongjmp1: SIGSEGV set

Dunno if that's related (just ran it and now I'm running off to a
meeting :-).
