The test is crashing in a flaky manner. It started doing so after the libsoup Jhbuild dependency was bumped in r137286
http://trac.webkit.org/changeset/137286

The update bumped libsoup from the 2.40.1 tag to the 5651d18e commit.
http://git.gnome.org/browse/libsoup/commit/?id=91efda67678dbad28603ee8034a10cc6081f4b8d
http://git.gnome.org/browse/libsoup/commit/?id=5651d18eb8c9edff5961a32c488641bf6776ca6b

Glib was also updated in that patch, maybe the fault is there.

This test only crashes on the 64-bit release builder. That system has 24 cores so there are possibly other tests being run before this crasher which basically just set up the conditions in which the crash then occurs.

Here's the crash log, indicating file descriptor excess.
