I would like to use tmpfs for all the package-compilation

if I use more than 512MB for /var/tmp/portage...
OMG, I was really over-optimistic! Even 2 GB tmpfs for
/var/tmp/portage was not enough to re-compile gcc-4.7.3!
In case someone is interested, I created /var/tmp/portage
as 4GB-big tmpfs, and then recompilled @system. I checked
how much /var/tmp/portage space is needed for each pachage:
gcc-4.7.3-r1: ~2.4 GB
glibc-2.17: ~490 MB
perl-5.6.13: ~250 MB
binutils-2.23.2: ~300 MB
And a few from my @world:
php-5.5.7: ~540 MB
mysql-5.1.70: ~420 MB
Packages not listed needed less than 200MB and/or were
compiled fast and not recorded by my script (it checked
/var/tmp/portage every 5 seconds).
