Darcs uses a lockfile to avoid multiple write accesses to the same
repository.  The locking strategy used by Darcs is believed to be safe
against race conditions:

 - on local filesystems, under both Unix and Windows;
 - on NFS mounts (even NFSv2), under Unix but not necessarily Windows.

I do not know whether our locking strategy is safe on SMB mounts; I
believe it depends on the details of the SMB implementation.
