I think the previous is superior in at least some cases ... I have a
config snippet (below) which I tried to use to flash the titlebar of
urgent windows; it works OK, but causes focus weirdness (I think) due
to the grabs on some slower machines. While the window is flashing,
occasionally keystrokes will be lost when the coincide immediately
with a colorset change. I think the first option above would
alleviate this.
