- Update to version 3.3.1
* Fix a locking order bug that could cause deadlock during fork
if heap profiling were enabled.
* Fix a chunk recycling bug that could cause the allocator to lose
track of whether a chunk was zeroed.
* Fix TLS-related memory corruption that could occur during thread
exit if the thread never allocated memory. Only the quarantine
and prof facilities were susceptible.
* Internal reallocation of the quarantined object array leaked
the old array.
* Reallocation failure for internal reallocation of the quarantined
object array (very unlikely) resulted in memory corruption.
* Fix Valgrind integration to annotate all internally allocated
memory in a way that keeps Valgrind happy about internal data
structure access.
* Fix building for s390 systems.
