- is the event queue the struct QUEUE with handling in tsq.c?
- and - as this is thread-safe - this seems to imply, that we goona do
event handling in the main thread which then dispatches signal events to
the appropriate thread. This seems reasoable for pthreads with POSIX
behavior. But the implementation in linux does/can direct signals to the
causing thread.
- OTOH we have per interpreter events e.g. Timer, IO completion
- Finally: how will we construct an event in a signal handler. AFAIK you
can't malloc it in a sig handler. Should we generate a pool of event
objects in main code, and then use these preconstructed objects in the
sig handler?

TIA
