Sebastien is currently working on splitting out the GL backend for
natty, to work around this. Therefore this isn't release critical any
more for the nvidia driver.

the difference in that version of cairo is that the gl backend required

Just to see did go ahead and package/install the current 1.10.2 source
without gl enabled, it brought the mem use at log in back to the
expected amount. (246 vs 602MB, unity login on this machine, slightly
greater diff on the affected p4 1GB
As it stands now, machines w/ 2GB or more doesn't
Ok. So, a little bit more digging shows that the mere act of loading
nVidia's libGL dirties ~5MiB of memory on AMD64. Multiplied by each
process linking to cairo that's going to add up to real money pretty
soon.
Unless we get cairo to dynamically load libGL when an application
requests a GL
And looking at cairo-gl, dynamic loading libGL is not a week-before-beta
