I am debugging a KLD.  After each run, there is always some memory in use
as indicated by vmstat -m. In other words, some memory are still in use by
the KLD. Is there any way to detect the memory leak?

After I do kldunload, all memory used by it is gone.  But I doubt that the
memory is actually returned to the global pool. Probably, it is only the
statistical information is gone.

Any help or suggestion is appreciated.
