I have noticed this problem too, but in my case mfs is the culprit. My
/tmp is a mfs: I can fill the swap in creating a large file on /tmp and
then deleting it. There is something strange though: I swap on wd0 and
sd0 and /tmp uses sd0. If i creat/delete a large file on /tmp, this
also fills wd0:
$ swapinfo -k
Device      1K-blocks     Used    Avail Capacity  Type
/dev/wd0b       20480    20068      348    98%    Interleaved
/dev/sd0b       58968    19712    39192    33%    Interleaved
Total           79320    39780    39540    50%

(after a 19Mb file creation/deletion)
