I had a similar experience under Windows. Never really got to find out
why it happened. You might try adding a short threadDelay call in your
main loop and see what happens; I think it helped back then.

Haven't heard of any. Note that Param is essentially the same as
combining the Simple variant with a reader monad layer, so it shouldn't
affect the basic operation of the library.
