Re: darcs patch: forkChild, waitForChild, parIO, timeout

This seems like a good place to use DiffTime, from Data.Time.Clock. That way, you can specify timeouts using (fractional) seconds and avoid confusion as to whether timeout uses microseconds, milliseconds, or nanoseconds. Unforunately, Data.Time.Clock is in the time package. An alternative is Micro, from Data.Fixed. -- David Menendez http://www.eyrie.org/~zednenem/
