Absolute standard request, has nothing to do with Python. The way to go
(in Cish pseudocode) is:
thread() {
/* do work */
[...]
/* finished! */
semaphore++;
}
semaphore = 2
while (jobs) {
semaphore--; // will block if pool exhausted
thread();
}
// in the end, collect remaining two workers
semaphore -= 2 // will block until all are finished
Best regards,
Henrik
