It just does this:
tscrim@travis-apricot:~$ sage

The above exception was the direct cause of the following exception:

Thus I cannot debug Cython errors unless I run "sage -b", which takes
forever because the meson setup takes multiple minutes every time.
Two things we (specifically the people changing stuff in the build system)
**really** need to do because this is unsustainable for Cython development
in Sage:
1) Figure out what makes meson take so long to do its thing each time "sage
-b" is run because this significantly slows many things down.
2a) Display the error message when cython builds fail so we can debug
cython errors with the magic compiling. (I still *very* strongly believe we
should give a message saying Cython code is recompiling verbosely on the
files so it doesn't look like it is hanging. I also believe it is bad
practice to make a non-jit-compiled language act like a jit-compiled
language, but that is secondary.)
2b) Revert "sage -b" to actually just rebuilding the parts of Sage that
should be rebuilt/recompiled; meson is not part of this AFAIK.
