Re: How can I force thread switching?

In Java, calling Thread.yield() (or, alternatively, Thread.sleep(0)) does what you want. I’m not sure how to do the equivalent in Perl, but if sleeping for one micro-second is more acceptable, you may want to look at Time::HiRes.

I have already explored Time::HiRes since `usleep()` is defined in this package. I also attempted to wait for 0 unit of time (second or microsecond) to no avail. The null delay is probably detected somewhere and optimised out. As stated in the manual, `yield()` is a no-op on most systems.	[reply] [d/l] [select]

BrowserUk says yield is a mistake (like sleep 0), so sleep more, like 1/2 (or less) of the minimum time period that you believe it will take, like 33 milliseconds -- seems to hold true on win32, good rule of thumb :)	[reply]
