Upgrade urgency CRITICAL: This release reverts back the Jemalloc upgrade
that is believed to potentially cause a server
deadlock. A MIGRATE crash is also fixed.
Two important bug fixes, the first of one is critical:
1. Apparently Jemalloc 4.4.0 may contain a deadlock under particular
conditions. See https://github.com/antirez/redis/issues/3799.
We reverted back to the previously used Jemalloc versions and plan
to upgrade Jemalloc again after having more info about the
cause of the bug.
2. MIGRATE could crash the server after a socket error. See for reference:
https://github.com/antirez/redis/issues/3796.
