As part of a research project we're using sage as a subroutine for some matrix
computations over rings. We have hundreds or thousands of these computations,

is fairly quick. Right now, for each computation we write python code into a .sage file,
and then start a new process with "sage somefile.sage > output". This works
fine, except
each time we incur the startup time, which is about 2.5 seconds (whereas running a
tiny python program is < 0.02s). Since we call sage hundreds of times, this
adds up pretty
quickly.
In Sage - actually in Python - you can handle exceptions:
L = [2, 0, -3]
for x in L:
try:
print(1/x)
except ZeroDivisionError:
print("Can't compute inverse of %x." % x)
so why you can't just make you C++ program to output, say, 10000 of matrix
computation to a .sage file having some try-except -structure on them?
