You're right. Using standard-thread would let me simplify my
event-handling code, since standard-threads are threads, whereas
delay/threads are promises, but it doesn't make much difference.

I think my request for threads to remember what killed them may have
been premature. I hadn't considered the security aspects of the
situation: it might be a dangerous leak to have exception information
available to all comers upon mere presentation of a thread handle.

There might be a revised design that separates the kill/resume/etc
capabilities already built-in to thread handles from the reflection
capability that'd be needed to get information on what killed a thread,
but absent that, and for now, standard-thread will do fine.
