Yes. libopen searches in directories specified by a set of environment
variables and some of these directories may be on NFS mounted volumes
(also the library being loaded may have dependencies - causing other
libraries to get loaded, etc - taking quite a bit of time).
Not sure about find_name() - image symbol tables are already loaded by
libopen - so I guess it cannot block.
