Hmmm,

I run regularly "make testlong" on my old G4 PowerPC Mac, and that
system has only 768 MB RAM. Last time is just a couple of days ago
with Sage-4.7.2, and e.g. heegner.py did pass OK. (There were only
four failures in total, two w.r.t. intefacing: maxima.py and sage0.py,
and two timeouts for elliptic curve computations:
ell_rational_field.py and sha_tate.py).
So there must be something different going on.

@Maarten:
Does the output you pasted mean that there is no swap space at all
("Swap:            0          0          0 "), i.e. neither an extra
swap partition (fstab/mtab might show more info on this) nor some swap
file? Even my old Mac swaps out memory pages to disk ...

Cheers,
Georg
