It is not so much the build time that the memory consumption which I found
problematic. It is becoming difficult to build scipy on my laptop with 512 Mb
(compiling the sparsetools_wrap.cxx with gcc -O2 takes around 400 Mb, and some
compilers are even worse), or on virtual machines.
Is the patch really that invasive ? Splitting in 2 or 3 would already be good if
the memory consumption reduction is decreased by the same order.
