Are you talking about a signal handler than runs exec()?  Or how are you
planning to implement this?  I'm wondering what the advantage is over
having a "restart" option in an rc script that sends SIGINT to the running
server and then starts a new one.

If you're willing to wander off from the tourist trap signals, there is
SIGPWR on Solaris, Linux, et al.  I just glanced through the signal.h
files and that seemed to fit what you're doing -- "power cycling" the
slapd process. Hardcore compliance people will no doubt blanche at the
notion...
