Comment(by malb):
I decided to take another look. In the attached patch I move most of the
functions in {{{multi_polynomial_ideal.py}}} to the new libsingular
functions interface which does not need pexpect or IPC in general.
On my Macbook Pro vanilla Sage 4.3 takes roughly '''48''' seconds to
doctest {{{multi_polynomial_ideal.py}}}. With the attached patch applied
it takes '''26''' seconds. I'd expect bigger improvements on machines with
slow I/O (e.g. disks).
As a side-effect, a lot of the ideal operations are considerably (100x and
such) faster now and the libsingular functions interface is more robust
and handles more functions now.
Note that I tried to be a bit smart about the creation of the libsingular
functions. One can now do:
{{{
sage: primdecSYZ = sage.libs.singular.ff.primdec.primdecSYZ
}}}
which will load 'primdec.lib' first and then create a wrapper for
{{{primdecSYZ}}} in that library. A referee should also register whether
he/she likes or dislikes this interface.
The attached patch requires an updated SPKG which is available at:
http://sage.math.washington.edu/home/malb/spkgs/singular-3-1-0-4-20100120.spkg
I didn't mark any doctest {{{#long}}}, in fact, I added some doctests!
