txul regression of varying degree across almost all platforms around the same time: http://graphs.mozilla.org/dashboard/. possibly related, given the timeframe.
backtracked on the tinderbox, found the last good run and first bad run for talos-rev2-leopard07. here are the changesets in that window: Use gcc-4.2 and the 10.5 SDK by default in Gecko 1.9.3.

This caused a bit of a Ts regression but most of it was likely due to bug 517549, which this caused because it turned on expensive 10.5 TIS calls by accident. That has been fixed and now Ts is much lower than it was before this bug. This would not have caused a Ts regressions on other platforms, as discussed in the perf regression bug.
Oops, I meant to post comment #6 in bug 501436.
thanks josh -> duping against bug 517549
