[Intel-gfx] bo problem, file-max limit reached within two days

[Knut Petersen]

After a few unattended hours Xorg was still running,
but only a terminal window had survived the night :-(

Xorg: git, a few days old, kernel: 3.3.

Xorg.0.log: Nothing unusual

I built a new X server and tried kernel 3.2.12 - that does not seem to help as
both the number of open files  and the number of gem objects still grow without
obvious reasons.

Any idea?
