a PerlSetVar foo following a PerlAddVar foo is supposed to reset the value
of foo, clearing the previous array (IIRC)
might be worth noting...
also, once you use the Apache::Table interface for either, you can call
set() in addition to add(). Doug thought that this might only set it for
the lifetime of the child, not permanently. I haven't verified this either
way (only that it works for my needs :)
