Doc Text:
.Python tasks no longer wait for the GIL Previously, the Ceph manager daemon held the Python global interpreter lock (GIL) during some RPCs with the Ceph MDS, due to which, other Python tasks are starved waiting for the GIL. With this fix, the GIL is released during all `libcephfs`/`librbd` calls and other Python tasks may acquire the GIL normally.
