Yep, that's your problem. forkIO the hPut.
Maybe I didn't do enough here -- just wrapping in `forkIO` does not seem to actually help.
*sigh* I hate the ghc runtime... it works in ghci, or compiled with - threaded. Otherwise you still get the deadlock because it only switches threads under limited circumstances (garbage collections?) which isn't nearly often enough. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
