There is one other wrinkle, that has just come to my attention courtesy 
of Andrew@SuperNews. This is what the perlembed man page says:
      Now suppose we have more than one interpreter instance running at the      same time.  This is feasible, but only
ifyou used the Configure 
 
option      "-Dusemultiplicity" or the options "-Dusethreads -Duseithreads" when      building perl.

Now my local perl (FC5/ia64) has usemultiplicity defined. I am not sure 
how common this is.

Perhaps people who use other platforms could look for these flags in the 
output of   perl -e 'use Config qw(myconfig config_sh config_vars config_re); 
print config_sh();'

cheers
