I noticed elsewhere a mention of Neil Katin's memory leak fix in 5.0.86. Is
the CLIENT USER_STATISTICS patch described below that patch? (If it is, I
will quit  pursuing the fix, since I have already incorporated his fix in
our source tree. Thanks, Neil!!)

Our system administrators report that there might still be a small memory
leak in our mysql servers--it appears in a few of our boxes. If you are
aware of other memory leaks in any of the Google or Percona patches, I would
appreciate hearing about them, so I can compare the changes with our own
code. The leaks *might* be in vanilla mysql itself ...??

Thanks for everything that all of you do! I really appreciate it!
