This release adds a progress message for one more errno value (EAGAIN) in response to failed mlock; BSDs use this to indicate the lock failed due to being over a system or process limit, much like ENOMEM.
_FILE_OFFSET_BITS is now defined as 64 bits by default in conf-cc, which causes some 32-bit systems with larger than 32-bit address spaces to have a 64-bit off_t, allowing testing of larger chunks of memory. Tests of 8 and 16-bit wide random writes were added to enable verification of the correct operation of hardware. If these tests trigger unaligned access problems on your platform, they can be eliminated by removing the -DTEST_NARROW_WRITES definition from the conf-cc file.
