Actually, I now count spacefor as a failed approach, and am in the early
stages of doing something better.  The problem is that there is far too
much senseless diversity in df output format, much more than I thought
in my young and innocent days. :-)

In the works is a version that puts the actual space-finding in C, using
the two or three different flavors of how-much-space-is-there system
calls, but keeps the choice of threshold out of the C code so it's easy
to change.  It's tricky to get all this right, especially with a df-based
fallback for really old systems, but I think I know how to do it, and it
should be significantly less hassle than relying on df.  Sigh.
