Cscore uses many global variables and it is large, ugly, old, and
rarely used so no one bothered cleaning it up so far. The PostScript
graphs should be easy to fix (there are 1-2 statics there or so, it
is just rarely used and got no attention). Of the plugins that do not
work in multiple instances, many depend on third party libraries and
the libraries themselves may often use global variables. It should
be possible to fix the Maldonado soundfont opcodes, as those do not
use any external libraries, although the code is really awful and
global variables is just one of the issues that need to be cleaned
up. Finally, some of the utility plugins may use globals; at least
cvanal and pvanal should be OK, however.
