edebug doesn't always work

[Joe Corneli]

Sometimes when I run `edebug-defun', the echo area displays
a messages that indicated that the function has been 
instrumented, but then edebug does not take over when the
function is called.  

I don't know what causes this behavior, and I'm looking for
suggestions.  The only workaround I've found so far is to 
restart Emacs (or to do all my debugging "by hand")!
