ktrace showed me what was happening. This isn't my favorite thing about

Is there even a means provided to set it back to blocking?
There isn't a way right now to open a file using a blocking FD, however
the IO library does support using blocking FDs (the std handles are left
in blocking mode to avoid causing problems with pipes). We could
certainly add an interface to let you open files in blocking mode - just
submit a feature request via GHC's Trac and we'll try to get around to
it (or better still, send us a patch... the code is in
GHC.Handle.fdToHandle).
Cheers,
