It would be nice to replace all access of fp with getfp() and have it release.
It would make a lot of sense, and perhaps it could also be used with a
lock system to make it closer to possible to push down the lock for
this area. Processes could share file descriptors in SMP and not
have race conditions there! I like lockmgr (maybe I'm insane...) but I'd
like to know if there's anything faster that works. Didn't you say
something about qlocks a long time ago? I wouldn't mind having a
faster lock.
