Hm.  Dunno.  I see them in a thread listing I wrote based on
##sys#all-threads.  (In fact, I'd like to suggest a different interface,
since it's not so easy to see where threads are blocked.  A
##sys#fold-threads would be great.)

A had a shallow read on the code and I believe that at least
thread-terminate will not clean up timeouts.  Unsure about i/o but the
scheduler code uses ##sys#thread-basic-unblock! and I haven't found the
spot where the corresponding timeouts are cleared.  (Same goes for my
bad fd handling code, which is triggered quite often here.)
