Ok thanks, I am wondering whether running multiple instances of R
would be possible without problems in presence of compiled code
(shared libraries).
Intuitively, while there can be multiple instances of R, all of them
would be using the same library, but I am just guessing, I might do a
check on this.

Ciao
