I'm getting bad behaviour with small threaded programs (not really
linux java related, but ...).

The mmap(2) size argument looks incorrect ...

This program was compiled on a CentOS 4.2 (RHEL clone) x86_64
machine. It seems to be an amd64 linux compat issue as the same
program runs fine on NetBSD/i386 using linux emulation.
