That brings me to a suggestion - would be nice if both Pyrex and Cython
could detect changes in .pxd files and use that to trigger compilation
of the associated .pyx files and all other files which cimport from
the .pxds.

As it is, if I change a .pxd I have to manually touch its .pyx. Worst
case is I have to nuke the build dir and make from scratch.
