I have and I am puzzled too.

Could be something with GHC's thread scheduler (is it fair?).
I have some ideas for workarounds, but I didn't get around
to trying them. For example, I think that unpickling too many
messages simultaneously put too much pressure on memory, cache and GC.
I don't really have the time to test my serialization libraries with
Joels code - mostly it's this unicode that scares me off (should it?).
Maybe I'll try to simplify things on my own.
I am searching for a programmer who is good at least in some of
[Haskell, ML, C++, Linux, FreeBSD, math] for work in Warsaw, Poland
