huge amount laundry memory not being cleaned up

hi there,
i've got a workstation running CURRENT that recently ran out of swap 
space.  i killed the usual suspects (chrome, firefox and thunderbird) 
and noticed some odd behavior.  while some memory did get freed up - 
after leaving the system idle for 4 hours i still have 14G or memory in 
the Laundry according to top.  I also have noticed that very little data 
has paged out of swap (100MB out of 2G).


i was wondering if there was a good way to determine what is in the 
laundry, or get diagnostic info on why it's not cleaning itself up? 
when i've seen this before only a reboot will get the system back to 
being stable, if i re-launch my desktop apps they'll quickly start 
trying to page out to disk again creating an OOM condition.

system has 32G of RAM and is running this checkout
FreeBSD topanga 14.0-CURRENT FreeBSD 14.0-CURRENT #66
