# How long to wait before giving up waiting for the mount to finish (seconds)

# If mnt already exists, then the previous run may not have cleaned up
# properly.  We should try to umount and remove the mnt directory.

# Wait for files to show up
# hdiutil uses a helper process, diskimages-helper, which isn't always done its
# work by the time hdiutil exits. So we wait until something shows up in the
# mnt directory. Due to the async nature of diskimages-helper, the best thing
# we can do is to make sure the glob() rsync is making can find files.
