I hope this helps you . The Windows VFS does not implement Mutex locking, and there is no other such VFS for Windows.
You have to implement that VFS yourself, or simply modify your own DB functions to lock a mutex around all transactions.

this will help flock the directory itself — then you never need worry about where to put the lock file:
code :
import errno
import fcntl
import os
import sys

# This will work on Linux

dirfd = os.open(THE_DIRECTORY, os.O_RDONLY)         # FIXME: FD_CLOEXEC
try:
  fcntl.flock(dirfd, fcntl.LOCK_EX|fcntl.LOCK_NB)
except IOError as ex:
  if ex.errno != errno.EAGAIN:
    raise
  print "Somebody else is working here; quitting."  # FIXME: logging
  sys.exit(1)

do_the_work()
os.close(dirfd)
