That's a neat idea, but just have to be very careful here. Currently, the
code does a ReadFile, queues the signal, and then a WriteFile. Calls to
raise and/or kill to a process with a blocking signal queuing, as written,
would fail, and take up to a second to do so.

Also, and more pertinently, you may want to block some signals, but allow
others through. Not sure how you imagine this would be handled, at least
with a single event object, although perhaps I've misunderstood your intent.

Cheers,
