You are correct that the main problem is in trying to fork when not

But with Tcl exec, you never call fork, screw around and then call exec*(), do
you? Is this an issue for C level tcl? Maybe the issue is that fork and exec
are separate calls, and something unplanned could happen between the two, and
pthread_atfork makes the two calls atomic. (And maybe sometimes even this
isn't enough?)
Obviously we can now use nsproxy to call exec. I'm not sure if it works for
every use of exec inside a full AOLserver, but it would be pretty close.
