Found that in 690469 I dropped 
    BasicManager()->DestroyedThebesBuffer(BasicManager()->Hold(this),
                                          mBackBuffer);
which was collecting dying buffers and deallocating it.

Looks like that part need to be moved back, otherwise we are leaking thebes buffers

This fix looks OK, but why wasn't the leak caught by any of our tests?  Were buffers actually leaking during reftest-ipc but not being caught, or do none of our tests exercise the path that was leading to a leak?  We need to make sure this doesn't happen again.
yep, that is interesting question...
that leak is very easily visible in about:memory reporter.... but reason is that we don't run IPC-reftests on debug linux builds... only on opt builds... that is why we don't run leak enabled test-run...
