looks like boost::mutex doesn't have the problem (when used with unique_lock). So I guess the problem is in shared_mutex.

I wrote this test code to reproduce. I get the still-reachable problem if I use either the read() or the write() call (shared_lock or unique_lock). Multiple calls to these functions  did not increase the number of reachable bytes in the valgrind report. I understand my previous use of adopt_lock was undefined (hence i've not used it here). Is my use as described by the code correct now ? If so, is this a bug ? >    It is almost certainly exactly the same as with shared_lock.  The code that allocates the object is in a lower level component.
