You may try to run some lines of the tests in an interactive Sage
session and see what happens, perhaps after first running the doctests
with --verbose (although output is currently not flushed properly).
I have seen strange things.
First, sometimes, I don't get a timeout: it ends (in less than five
minutes), but some tests fail.
Second, what are the failure when it doesn't get stuck?
Here is one trace:
Exception raised:

As far as I know, what happens in .sage/temp/newton/<pid> is that some
functions get compiled on the fly, and the two traces seem to mean
something goes wrong there. The fact that sometimes I get a timeout on
the file could also be a case of that.
Does that make someone go "Oooooohhhh!" ?
In any case, as is, 2 GB are certainly not enough to run the (long)
doctests of that file.
That is a lot of memory. Can't those tests be modified to need less?
