Comment (by vdelecroix):

 Replying to [comment:3 ncohen]:
 > Hmmmmm... If it always hangs on infinite groups, what about raising an
 exception in that case instead of waiting forever ?

 Done. But I do not know if it hans for '''all''' infinite groups. You can
 decide conjugacy in many groups (e.g. SL(2,Z) and its finite index
 subgroups, free groups and its finite index subgroups).
