So the sequence:
  ...
  g_vfs_open(...);
  g_vfs_close(...);
  ...
works fine.

What r u doing between the mount and the unmount calls?
Maybe something changes, so that ...close() deadlocks?

Did u try to put debug printf's in the g_vfs_close() function? :-)

Or is there a program somewhere, that uses g_vfs_open/close?
Maybe u could learn/copy&paste from hpfs?
