Here is a small program that I can use to consistently reproduce the 
problem.

Save both files into the same directory.  Open wait-student.ss in 
DrScheme.  Insert a space (modifying the file).  Now press Check Syntax 
and quickly press Save (once will do).

This program uses wait.ss to cause an expansion time delay, giving you a 
chance to save while check syntax is running.
