RE: preemptive getLine on cygwin?

I seem to have some problems understanding preemptive getLine behaviour on cygwin, and wonder whether this is a known/fixed bug/feature (I haven't switched to ghc-6.. yet), or whether anyone has experience with this (behaviour on solaris, with an even older ghc is more or less as expected).

You're running a fairly old version of GHC. With 5.04.3 here I get different behaviour, although strangely it seems that stdin and stdout don't default to LineBuffering in a cygwin shell window. Cheers, Simon
