I accidentally looked into ghc/lib/std/cbits/getLock.c. I don't know
whether this is the reason of the above trouble, but it's horrible:
it blindly adds an entry to writeLock and readLock arrays without
checking for array index overflow. And as I understand it, the
tables may have different sizes when ghc is compiled in different
environments, yes? I have FD_SETSIZE = 1024 here, I don't know what
is in the precompiled ghc.
