4021	Problem of Interaction Between the FreeBSD Kernel and the GHC RTS	pgj	pgj	"There is a process (throwto003, test 173) during running `gmake -C testsuite/tests/ghc-regress BINDIST=YES` on FreeBSD which eats up all the available memory in the system and then killed by the kernel.

Excerpt from the log of testsuite:

{{{
...
cd ./concurrent/should_run && ./throwto003 +RTS -N2 -ls -RTS </dev/null >throwto003.run.stdout 2>throwto003.run.stderr
Wrong exit code (expected 0 , actual 1 )
Stdout:
Stderr:
throwto003: out of memory (requested 1048576 bytes)
*** unexpected failure for throwto003(threaded2)
...
}}}

Note that it works as expected when using `WAY=normal` or `WAY=threaded1`.  It means that the `-O` flag may cause the problem.  It appears on both x86 and x86_64.  The log was generated on an Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66GHz, inside a chroot(2) environment with a vanilla 8-STABLE kernel (as of February 17, 2010) and 8.0-RELEASE userland.
