No, I intended to match function types to allow a seemless transition.
 This is a bug.  Still, I'm questioning the value in supporting a
compatability API for a depricated package - especially seeing as it
depends on the unsafePeformGlobalBadness hack.   I could add a module
Control.Event.Relative to allow relative times using just forkIO and
threadId (a lighter weight solution than the current bloatware), but
that would just use IO and no STM.  What would be useful for your
network-dns work?

Documentation for Control.Event.TImeout?  I assumed that people using
the module would be familure with Control.Timeout - perhaps its time
for that assumption to change.
