    _______________________________________________________

Details:

See attached example for minimal working example.  The function creates a
variable in its caller's workspace, it then calls a script in the callers
workspace and tries to print out the value of the new variable.


> isolate
A =  10
yes variable A does exist
A =  10


isolate.m contains a simple test.  "test isolate" works the first time:


> test isolate
A =  10
yes variable A does exist
A =  10
PASSES 1 out of 1 test


But subsequent runs fail:

> test isolate
A =  10
yes variable A does exist
  ***** test
 isolate()
!!!!! test failed
'A' undefined near line 5 column 1


"clear all" makes it work once again.  Its also a bit non-determininistic!  At
least my more complicated examples are: might work twice if I make some
whitespace changes to my .m files for example.

Probably this has something to do with how the tests are parsed and processed,
but its got me stumped!
