4k on the MIPS boards I'm using. The SPARC I tried on is 8k, but LMDB
0.9.11 from git uses sysconf(_SC_PAGE_SIZE) to get the page size at run
time so that shouldn't be a problem.

The SPARC and MIPS problems may or may not be related - I just tried SPARC
since Howard mentioned it worked. Do you know a known-good version on
SPARC? If so I can work from that and see if I can find the commits that
introduced the problem.
