It is happening right now, and here is the system load:
top - 10:07:19 up 1 day, 19:46,  4 users,  load average: 0.28, 0.30, 0.16

It has been like this (i.e. the delayed workspace switch) as soon
as I loged in 1 day and 19 hours ago!!

Makes no difference here. Right now, I have no firefox running.
And thunderbird's cpu load is too small to be shown in the terminal
window in full screen mode (98x31 - I have to use large fonts).

But how can I prove it? Is there a way to instrument the
Xorg driver to leave a timing trail in a large circular buffer
for the workspace switch events? and then dump the buffer
to a file after N many events?

See above. Xorg got upgraded to fc14 about 1 day and
22 hours ago.

But I did not change any configuration between fc13 and fc14.
