Is there something wrong with the way I'm implementing the pause

My guess is you are crashing due to stack overflow.

I expected the problem was that vwait waits for the local variable
vpause while the after sets the global variable vpause. The vwait
man page also indicates that the variable must be "globally scoped
(either with a call to global for the varName, or with the full
namespace path specification)." However, my experiments seem to
contradict this. Does vwait always work on global variables? Was
this changed at some point? Shouldn't the man page then also be
updated?

Schelte.
