If you're running a non-threaded build on Unix, try it again in a
threaded build, and see if that improves the situation. There's
a long-standing problem that the arrival of Tcl_AsyncMark in
a signal handler in a non-threaded build will not interrupt the
select() in the event loop.

A work-around, if signal response times of a few milliseconds
in an idle process are OK, is to have a "do-nothing" timer event
that reschedules itself every few milliseconds. The async will
be detected once the process is no longer idle.
