[Leaplist] major bug found in Linux to give root access to untrusted users...

[Richard F. Ostrow Jr.]

All I'm saying is (a) know the system, and what it means, and (b) have a
reason for setting it where you set it. 4096 is the default in recent
kernel sources from kernel.org, and as such I can see that as valid.
65536, on the other hand, makes no sense to me whatsoever. It's either
zero or non-zero, and the lower the better.
