Well, and no.  There have been bugs in locking, of course, but the
basic design has always been sound and the implementation has only
rarely been excessively fussy about locking.  In fact as far as I know
most of the write operation (ie, repacking) is done without locking
the repo; the history data is written to temp files, and locks are
held just long enough to update the metadata atomically.
