You can have as many Info buffers as you like, just rename them to
*info*<NN> where NN is a number.  Then you can invoke
info-display-manual and get back to the manual you want, or even use
"C-u NN C-h i" if you happen to remember the number.  I routinely have
several dozen Info manuals in my Emacs sessions.
