This timeout seems to be reprodusible for Mac with slightly different switches.

> Tools/Scripts/run-webkit-tests --debug --no-build  --iter=300 --no-retry -v --child=2 -f http/tests/multipart/invalid-image-data-standalone.html

[151/300] http/tests/multipart/invalid-image-data-standalone.html passed
[152/300] http/tests/multipart/invalid-image-data-standalone.html failed unexpectedly (test timed out, text diff)
[153/300] http/tests/multipart/invalid-image-data-standalone.html failed unexpectedly (test timed out, text diff)

It seems to be reaching the CGI process limit.
Replacing wait=100 with wait=3 resolves the problem.
