Yes, that describes what I was seeing.
About 40 tabs, half a dozen other application/windows open.

This was a laptop with just 2G ram which might explain the higher %-age

It took some discussions before finding.  The high level phenomena
(being triggered by firefox) and the low level cause (XSYNC) never seem
to occur together in the bug reports.

But then complex path interactions get like that.
