Trying to further improve #swad, and as I'm still unhappy with the amount of memory needed ....
Well, this little and special custom #allocator (only dealing with equally sized objects on a single thread and actively preventing #fragmentation) reduces the resident set in my tests by 5 to 10 MiB, compared to "pooling" with linked lists in whatever #FreeBSD's #jemalloc serves me. At least something. 馃檲

The resident set now stabilizes at 79MiB after many runs of my somewhat heavy jmeter test simulating 1000 distinct clients.
