For the big compiles I set PORTAGE_TMPDIR=/pt/ , which I have created
and which is NOT a tmpfs, so it will survive a reboot (and I don't have
enough ram anyway) . You might also want to check FEATURES, either
globally or on a per-package basis, make sure you don't have fail-clean.
Watch out so your newly permanent tmpdir does not fill up.

Then, if it dies for some reason, I do for example:

<code> ebuild `equery w www-client/firefox ` merge. </code>

make  or cmake or whatever will do the best it can to pick up where it
left off.

P.S: Search the web to find out to set FEATURES and PORTAGE_TMPDIR in
the environment on a per-package basis, or just prepend the settings to
your command-line.
