If we are reaping from the cache and a concurrent allocation occurs then the caller must block until the reaping is complete. This is signaled by the clearing of the KMC_BIT_REAPING bit. Otherwise the caller will be in a tight loop which takes and releases the skc->skc_cache lock. When there are multiple concurrent callers the system will thrash on the lock and appear to lock up.
