Since we've been looking into this now and we have a solution in our collective mental caches, is there please a chance to effect this change for this beta? I'm telling you, it is an _important_ step forward in unittesting D programs.

Thanks!

It's not hard to write a segfault handler that

feature.

syscalls are always legal because syscalls exit when signals occur 
(technically, they aren't even calls, they are software interrupts).  In other 
words, printf is illegal, write is not.

I think it's a bit more restrictive than that, but you're right.  If it helps, 
the list of signal-safe functions I use for reference is here:
