A common problem is the desire to have an action run at a scheduled interval,
but only if it is needed. For example, instead of having every web request
result in a new
getCurrentTime call, we’d like to have a single worker thread
run every second, updating an
IORef. However, if the request frequency is
less than once per second, this is a pessimization, and worse, kills idle GC.
This library allows you to define actions which will either be performed by a dedicated thread or, in times of low volume, will be executed by the calling thread.
For original use case, see yesod-scaffold issue #15.
