I like saying M_WAIT when I mean M_WAIT. I dislike saying 0 when I mean M_WAIT. The fundamental problem here is that M_WAIT looks like a bit flag. That problem should be directly solved by defining it to be a bit flag. There are no ABI issues with this in FreeBSD 5.x. Warner's proposal to automatically detect programming error is also a good idea. And, that relies on making M_WAIT a bit flag too. Let's solve the problem where it really lies by simply making M_WAIT a bit flag. Jeffrey To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
