I'm sure I understand you because of the following, but to make
absolutely certain...  you mean: locking shared structures from within
generic widget code (such as that defined by the GtkRadioButton) is a
terrible idea.  right?  (don't bother answering this question, unless my
head is really on backwards.)

Thank you very much for removing my confusion.  I'll let my simple
widgets continue to be non-thread-safe.
