Are you sure it's really a full recythonize and not just a rebuild of all
files depending on a common file like `src/ext/interrupt.pxi`? It's true
that Cython (just like `make`) uses timestamps to trigger rebuilds, so if
the timestamp of `src/ext/interrupt.pxi` changes, then all Cython
extensions depending on that (i.e. almost all of them) would be
recythonized.
If this is the problem, I would like to close this ticket as `wontfix`
since it's a feature, not a bug, to use timestamps for dependency
checking. And even if it would be a bug, it's in upstream Cython, not
Sage.
