> I remember having the same failure in free_module.py and I think its
most likely caused by having not sufficient memory - everytime I run
free_module.py's my system (i686 + 1GB RAM + 512 MB swap) is heavily using
swap.
Interesting. On the Arch VM where I was seeing the same problem,
increasing the RAM allocated to the VM from 1152 MB up to 1768 MB seems to
fix the problem. (Using 4.5.3.alpha2.) But there are still questions: why
do the tests pass when run in Sage normally? Does the doctest framework
really take 600+ MB of memory? And why exactly does Singular fail to start
-- is it just unable to allocate enough memory? If so, can we get a better
error message? These tests seem to work on non-VMs with less memory -- or
do they? Why is that?
