With RC4 I meant - as it's run-time enabled by default currently, that could be turned on by default in RC4 if everything was well in RC3.
Regarding possible build issues you mention - probably some magic in config.m4 could disable huge pages? I wasn't aware, but probably yep - like FreeBSD or OSX likely to not to have the sys/prctl.h . This could be a reason for delaying till RC4, but it's actually easy solved doing some test compilation in config.m4 . I'd see build + disable on run-time in RC3 as a better move because it turns the test circle earlier which is good considering there are only 4 RCs to go yet.
