Changed paths: M t/test.pl Log Message: ----------- t/test.pl: Fix threads signalling watchdog cancellation Commit 4712a4c94e5974bba8ef97d68aadf2b99c0b4ff4 added the ability to cancel a watchdog timer. Unfortunately it doesn't work properly when the timer method was using the thread signalling cancellation method. This problem only shows up on slow systems under load, so the flaw wasn't immediately discovered. That commit lowered the incidence level significantly. This commit solves the problem by having the child thread detach itself, after it sets up the needed code to handle a signal from the parent. The parent thread signals the child, as currently when it is done processing, but waits for the child being detached. That is a cue to the parent that it is safe to signal the child.
