Here's what you are after.
From the Stack Description:

 
                          GlobalMaster stack
 
                          by Frdric RINALDI
 
 
   This stack contains two XCMDs which allow to easily purge all global 
   variables created by the stack. They work only with HyperCard 2.0.
 
 
                      SaveCurrentGlobals 1.0
 
DESCRIPTION
------------
   SaveCurrentGlobals saves the list of current active globals.
 
   SaveCurrentGlobals must appear in the "on openStack" handler before 
   any global variable setting. 
   The XCMD creates a global named GlobalVarsList which will be used 
   later by ClearStackGlobals XCMD.
 
 
                      ClearStackGlobals 1.0
 
DESCRIPTION
------------
   ClearStackGlobals purges all global variables created since call 
   to SaveStackGlobals.
 

I haven't used these myself yet, so I can't vouch for them.
