Some very important bugfixes, like no longer saving the function address in map, because it caused all transactions to fail on a map. When attaching to existing map, check has been implemented to verify its integrity. Fixes were also made for a shmap_items wrong item count and an IPC semaphore leak.
The internal structure has changed a bit, possibility to attach to existing maps (requires the libmm patch). It is possible to set, unset, initialize, and destroy map locks at runtime.
