Hellooooooo !!
It seems weird that the loglevel has to be stored in *BOTH* iocp and smcp
`O_o`
Isn't just one of them necessary ? And you also thought of copying the
self.preprocessing variable but it is not the only one that can be set
with GLPK. The "timelimit" option is also exposed, and we probably can do
better than to store everything twice and redefine it in the new copy.
Isn't there a "GLPK way" to copy the content of a scmp object ? It would
be nice to let GLPK do the job, or we would have to create a new variable
each time we expose a new parameter `O_o`
By the way, I reinstalled Sage and tested the CBC patch, but of course it
still returns this "gzopen function non found" error message I told you
some time ago... And as the fix I had found does not work on your computer
we are not done yet `:-D`
