[jboss-dev] tmp/ delete

[Ales Justin]

Hmmm, the tmp/ dir actually gets properly cleaned up at shutdown.

After boot:

...
24K	tmp//vfs/vfsinmemoryf1bdac672661640a
6.2M	tmp//vfs
6.2M	tmp/

After shutdown:

Skywalker:default alesj$ du -h tmp/
  0B	tmp//aopdynclasses
  0B	tmp//deploy
  0B	tmp//vfs/automountb9cbfa289cf8ff71
  0B	tmp//vfs/automounte49dfcb2551ae11c
  0B	tmp//vfs/shrinkwrap-a64c8a721bc8e1b1
  0B	tmp//vfs/shrinkwrap-d4c2314266154a4b
  0B	tmp//vfs/vfsinmemoryaff1fe101cee6da1
  0B	tmp//vfs/vfsinmemoryf1bdac672661640a
  0B	tmp//vfs
  0B	tmp/


Nicklas is asking if we have "any windows-hosts doing hudson jobs that would show the behavior?"
