Maybe add your own read-only sysctl OID and then replace the
fork() syscall so it would increment the corresponding variable
accordingly at each run ? Read Andrew Reiter's or Pragmatic's
tutorials on hacking system calls. After that, take a look at pjd's
page, he has some nice stuff that also implements additional sysctls:

If it's there, and you can see it, it's real.
If it's not there, and you can see it, it's virtual.
If it's there, and you can't see it, it's transparent.
If it's not there, and you can't see it, you erased it.
