Description
I'm using BFS files for storing code and apps (for easy moving them around installations and backup). It seems like Haiku KDLs when trying to unmount image that was mounted for a longer period of time (more than hour?) and/or after multiple file operations (multiple makefile runs? or maybe because of multiple git commits?). Unfortunately it's hard to pinpoint it :(. This time it happened after multiple makefile runs, 2 git commits, restarting Deskbar (to make it "let go" my replicant app file on mounted file system) and unmounting file by right-clicking and selecting "unmount".
I did run checkfs on the mounted volume and it did not find any errors.
Not sure if it matters, but i'm running Haiku in VirtualBox, without any vbox addons (or guest helpers AFAIK, as i can't find any in HaikuDepot). I'm also getting KDL's in similar cases when working on disk partition (VirtualBox VDI disk) instead of file partition. But i don't have screenshot of that yet (sorry, did not make one before).
I'm attaching screenshot of KDL. Let me know if i can add some more info.

How to reproduce:
1) Create a ramdisk, format it as BFS and mount it on e.g. /ramwork:
ramdisk create -s 256mb
mkfs -q -t bfs /dev/disk/virtual/ram/0/raw ramwork
mountvolume ramwork
2) In haikuports.conf set
OUTPUT_DIRECTORY="/ramwork"
DOWNLOAD_IN_PORT_DIRECTORY="yes"
3) Build any package.
haikuporter -S uif2iso
or
haikuporter -S uif2iso_x86
(This is a really small program which builds really quickly.)
4) Try to unmount the ramdisk volume:
mountvolume -u ramwork
It will KDL almost everytime. This bug exists since a quite long time. It is still there, on hrev52355.
(If you repeat all the steps but skip the call to haikuporter then you won't KDL.)
This used to crash on all architectures.
On x86_64 hrev52355 it still KDLs everytime.
On x86_gcc2 hrev52355 it still KDLs from time to time.

The crash is is really a "warning" that objects were not freed from the cache. We should fix it, but we can probably disable it at least in the beta branch.

Remove milestone for tickets with status = closed and resolution != fixed
Forgot to add in description that it happened on hrev52323 now, but same (or similar?) KDL happened few time before to me. So at least since hrev52113.
Also it does not matetr if i have VirtualMemory disabled or enabled (it was happening with VM enabled, but i disabled it earlier today, rebooted, and KDL still happened anyway).
