skygw_logmanager_init is still useful because it allows for providing memory address for log manager where it can store a list of preallocated write buffers. TBD. Logmanager access is now protected with spinlock familiar from epoll/core/spinlock.c . It is modified to avoid trashing; misses are counted and every tenth subsequent lock acquiring attempt triggers short random sleep.
