I don't use X, but:
The swwrt state is induced by function swap_pager_putpages() in
src/sys/vm/swap_pager.c. It seems to imply that there's a certain
degree of swapping going on in/out of the process, but the code is
beyond my understanding. I see 621MB of swap used on that machine, so
it doesn't sound that far-fetched.
It would also help to know when your kernel was built (uname -a), since
there have been changed during the 8.2-PRERELEASE lifetime to the above
procstat -kk and procstat -v on PID 21787 might also be helpful.
