There are times where a patch is pushed to tryserver to make sure that an intermittent failure is fixed. In these cases, multiple passes of a test suite are requested, but the requester has to wait for the tests to begin running before they can request multiple runs. The try server syntax should be extended so that the initial request can state that multiple runs are requested. For example: try: -b o -p macosx64 -u mochitest-1[10.8],mochitest-bc[10.8]*3 -t none In the above request, mochitest-1 will be run once on 10.8 and mochitest-bc will be run 3 times on 10.8.
