More of a data point than objection, but that is splitting hairs. :-)
I'd say go, though it wouldn't hurt with more input on how things work on different OSes. http://pike.ida.liu.se/development/pikefarm/7.6.xml (build 662) says there exist green builds for linux ia64, sunos sparc, lots of yellow ones, and some reds. Should someone knowledgeable have time to write up a summaric overview of those (ranging from "known bad client setup" to "encountered error worth postponing release"), that's of course helpful.
