rtag and its locking behavior

[Dean Do]

Hello,

I have a question concerning the rtag command and its
locking behavior.  Whenever I run `cvs rtag` command,
it read/write locks the whole tree [all directories]
from everyone until it is done tagging every file.
Since our sw tree is quite big, this rtag process takes
~20min to complete.

Is there a way for me to change this rtag behavior where
it only locks one directory at a time as it tags the files
in that directory?  Once it is done tagging the files in
a directory, it should release the lock in that directory
and moves to the next one.  I can't find anything in the
CVS manual on this subject.

I'm currently running CVS 1.11.1p1 on Solaris8.  I would
appreciate any assistance in this.

Thanks,
Dean
