It turns out that we need to check for pending signals when a newly forked
process is run for the first time.  With strace -f, strace needs to know about
the forked process before it gets going.  If it doesn't, then it ptraces some
bogus values into its registers, and the process segfaults.  So, I added calls
to interrupt_end, which does that, plus checks for reschedules.  There
shouldn't be any of those, but x86 does the same thing, so I'm copying that
behavior to be safe.
