Hi John,

I'm getting the following error now:

Compiling...
[ 1 of 18] Jhc.AltIO        ./src/E/FromHs.hs:(869,4)-(871,30):
Irrefutable pattern failed for pattern (p : ps)

which is the irrefutable pattern in tinyHeads.  Unfortunately, I'm
still pretty clueless about debugging jhc itself.  I'm not sure what
this function is doing, or how to figure out which code it's working
on... :(

P.S.  You should be able to reproduce this using a darcs get
http://abridgegame.org/concurrency, and trying to build
jhc/Prelude.hs.
