stm-delay-0.1.1.2: Updatable one-shot timer polled with STM

This library lets you create a one-shot timer, poll it using STM, and update it to ring at a different time than initially specified.

It uses GHC event manager timeouts when available (GHC 7.2+, -threaded, non-Windows OS), yielding performance similar to threadDelay and registerDelay. Otherwise, it falls back to forked threads and threadDelay.

0.1.1.2 (2025-05-08)

• Remove a call to ensureIOManagerIsRunning, for consistency with System.Timeout
• Adjust timings in the testsuite to fix intermittent failure in the non-threaded RTS case.

0.1.1 (2014-09-14)

• Add tryWaitDelayIO, improve performance for certain cases of newDelay and updateDelay, and improve example.
