Albeit somewhat brute-force, Jonathan Rentzsch's mach_override can solve a lot of tough problems.

Just for the record, please don't do this is in any code that you intend to ship to end users. There's no way that Apple can maintain binary compatibility for KEXTs that do this.

I was looking at kevent. In userspace, the NOTE_FORK event seems to be
pretty close to what I'm looking for. Any idea if it (or similar) can
be accessed from the kext?

Alas, kqueues are not accessible from kernel code; they rely on descriptors, and the KPIs know nothing about descriptors. Worse yet, NOTE_FORK is horribly broken on all shipping systems <rdar://problem/3439519>.
