Comment(by jhpalmieri):

 > What happens if you run the test manually, on the Sage command-line?

 Well, right now I can't even get it to fail when running
 {{{
 sage -t -long "devel/sage/sage/graphs/genus.pyx"
 }}}
 by itself.  I can only get it to fail reliably if I use parallel testing,
 say
 {{{
 sage -tp 2 -long "devel/sage/sage/graphs/"
 }}}
 I tried running the testsuite from one window and "sage -t ... genus.pyx"
 in another, but that didn't fail, either.

 > Could this be a bug in sage.misc.getusage.get_memory_usage?

 Is it reasonable to get negative numbers for this?

 Should we change the test to
 {{{
 sage: get_memory_usage(t) <= 0
 True
 }}}
 ?
