There are two (or three?) sources of interittency here, and one of them is the testsuite harness itself. One thing you could do to try and narrow it down is to run *just* the test cases you are seeing intermittency in using RUNTESTFLAGS=foo.exp=bar.c a dozen times and see if the results are stable.
