Oran Agra c6a26519a1 fix a rare active defrag edge case bug leading to stagnation ... There's a rare case which leads to stagnation in the defragger, causing it to keep scanning the keyspace and do nothing (not moving any allocation), this happens when all the allocator slabs of a certain bin have the same % utilization, but the slab from which new allocations are made have a lower utilization. this commit fixes it by removing the current slab from the overall average utilization of the bin, and also eliminate any precision loss in the utilization calculation and move the decision about the defrag to reside inside jemalloc. and also add a test that consistently reproduce this issue.		2021-10-12 12:55:35 +03:00
