Thanks for letting us know. Please note, however, that this is not
the proper procedure to report bugs, see

  http://www.netbsd.org/Misc/send-pr.html

for details.

Since I could easily reproduce the problem, I took the freedom to file
a PR for this problem:

kern/29782: procfs can not unmount when some process has its current directory in curproc

Hope this is ok with you.

Thanks,

Martin
