As part of the BuildFaster project (see https://wiki.mozilla.org/ReleaseEngineering/BuildFaster), we are investigating whether certain slow mochitests can be sped up.
test_sessionhistory.html is a slow test, average execution time on a recent run (in ms):
Olli, as the original test author, would you be willing to help see if this test can be sped up?
Well, 7s or so is the 1000ms timeouts from nextTest(). I wonder why we need those.... Also some of the subtests have 1000ms timeouts.
Past that, this is actually tests for 7 bugs in 1.... I wonder whether any particular subtests are slow here.

This patch removes the 1s timeouts. It passed on try. Do you think it's safe to land?
