Ah, sorry, I misunderstood.

Yes, defining (thread-sleep/microseconds!) in a separate unit seems an
expedient way around the problem. (Or we could extend our SRFI-18 and
add this procedure there  -- just my two cents, but that seems like a
reasonable extension, given the commonality of compiling with
fixnum-arithmetic.)
