I'm not so sure that's the issue.  I checked out the sqlite databases
and they are relatively small, with the median being under 10KB, the
mean being about 24M, and the largest db about 32 M.

$ find ~/.mozilla/firefox/ -name '*.sqlite' |
xargs ls -ldSr |
tr -s ' ' '\t' |
cut -f 5  > file.csv
$ echo 'summary(read.csv("file.csv",head=FALSE)) ;' |
R --no-save -q
> summary(read.csv("file.csv",head=FALSE)) ;
 Min.   :    2048
 1st Qu.:    2048
 Median :    8704
 Mean   : 2390630
 3rd Qu.:   38912
 Max.   :31281152

If it were a db and/or ext3 issue, would I not see a lot of disk I/O
from the vmstat?  I see the CPU being maxed and virtually no disk I/O.
 No swapping, either.

Any ideas on how to isolate what the problem is?  Is anyone else
experiencing this?  If not, then maybe it's something fubared with my
