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.
