Yes, the failures would be intermittent (and often not easily
reproducible). The threaded index-pack code did not fail for
me on cygwin at all during development, including tests, but failed
immediately I installed v1.7.11. On real repositories, it failed
intermittently. On some repos it always failed, on some it never
failed and on some others it would sometimes fail, sometimes not.
