Is there a way to flush a thread's message box other than

flush from inside the thread? You could call receiveTimeout
with a 0 timer in a loop until it returns false.
Yes, from inside the thread. I have a worker thread (with
receiveTimeout) that is started when the program starts and
sits there waiting for input. I naively thought this was a
great idea, until I noticed that when input comes fast the
mailbox grows and the bloody thread won't stop until all the
items in the mailbox are processed. I was looking for something
like `if (abort) { mailbox.flush(); }`
void flushMailbox()
{
bool r;
do
{
r = receiveTimeout(Duration.zero, (Variant _){});
} while(r);
}
You could optimise that to more efficiently deal with the actual
types you're receiving, instead of making a Variant every time,
but it's probably not worth it. The compiler might even optimise
it away anyway.
