This patch reduces the running time for compaction_test from about 27
sec, to 3.3 sec, which is about an 8x speedup.
These numbers are for an Intel x86_64 system with 32 GB of DRAM.
The compaction_test.c program was spending most of its time doing
mmap(), 1 MB at a time, on about 25 GB of memory.

Maybe this should really be an RFC, given that I don't fully understand
why the compaction_test.c program was mmap'ing 1 MB at a time. So
apologies in advance if I've mucked up something important, but if so,
maybe we can still find a way to get this fixed up to something better.
