### MonetDB Common
- Threads have their own list of free bats. The list was not returned
to the system when a thread exited, meaning that the free bats that
were in the list would not be reused by any thread. This has been
fixed.
- Fixed a couple of deadlock situations, one actually observed, one
never observed.
### MonetDB5 Server
- Fixed interaction between mserver5 and remote mserver5 when only one
of the two has 128 bit integer support.
### SQL Frontend
- Fixed issue where equal column aliases were created. When those
aliases were parsed on the remote side it could give crashes.
