Locks are not "inherited". When dos under dosemu try to lock file or region 
of file these locks are not passed to samba server.

I use http://www.burtonsys.com/download/TESTLOCK.ZIP for lock tests. Results 
of such solution are below:

test        result   (test description)
-------     -------  -----------------------------------------------------
Test #1     Passed.  (Creating & modifying & deleting files)
Test #2     FAILED!  (Examining & modifying file attributes)
Test #3     FAILED!  (Enforced exclusive access, and share errors)
Test #4     Passed.  (Shared read access to files)
Test #5     FAILED!  (Shared modify access to files)
Test #6     Passed.  (File commit)
Test #7     FAILED!  (File region locking, and lock errors)
^^^^^^^^^^^^^^^^^^^
Test #8     not run  (Adjacent region locks, and lock/write conflicts)
Test #9     Passed.  (Appending & verifying new file sizes [NT 3.5 bug])
Test #10    Passed.  (Appending & verifying file sizes w/ closes)
Test #11    Passed.  (Appending & verifying file sizes w/ file commits)
Semaphore   Passed.  (semaphore-file kludge)
Test #3-A   Passed.  (Enforced exclusive access & share errors, 2-session)
Test #5&6-A FAILED!  (Shared modify access & file commit, 2-session)
Test #7-A   FAILED!  (File region locking, 2-session)
^^^^^^^^^^^^^^^^^^^

The same test on the same resource with client directly connected to samba 
(eg. on XP) passes all tests.
