mach in signal handler

Is it safe to use vm_region in a signal handler? I know there are a small list of functions that are considered safe <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man2/sigaction.2.html#//apple_ref/doc/man/2/sigaction> and vm_region is not among them.

I tried looking for vm_region in the darwin sources but I can't seem to figure out how to search the sources (clearly I'm missing something obvious here) and I can't find it looking where I expected it to be. Some man page leads me to believe that it's a syscall, yet I can't find it in any lists of syscalls in libc.
