This is a good idea to incorporate into OpenSM.

Any objections if this is bundled with SIGHUP handling rather than
SIGUSR1 which is not backward compatible as Sasha indicated ?

There may be additional option in this space (rotate or reopen, etc.).
I'll post an updated patch probably some time next week.

BTW, patches should be included as text rather than attachments. Also,
patches should be relative to trunk rather than something else (OFED
1.1). This all makes for more work for the maintainer to try to
incorporate these :-(
