The only commit in that window that affects the kernel is Tor's
filedesc_to_leader stuff.  A quick eyeball doesn't show any problems with the 
ulimit code in these commits, but I'm hardly an expert on this.

Perhaps Tor can comment?

[btw: the PR referenced in these commits (kern/50923) is still open.]
