Comment (by pgj):

 Thanks for the details.  I will keep trying to reproduce the problem.
 Based on my past experiences, I still believe that the problem comes from
 the FreeBSD base system, not GHC itself -- in such situations, I usually
 do some bisecting between the (kernel + userland) revisions to see which
 commit might have introduced the bug.  It may also happen (as you wrote
 above) that it is all about race conditions which may require a system
 fast enough to make them visible.
