Currently dev-libs/boost checks whether the system has 1024 MB of space before running its testsuite; this is wrong since the testsuite requires a whooping 20GB to run. Reproducible: Sometimes Steps to Reproduce: 1. FEATURES="test" emerge dev-libs/boost 2. test fails if you don't have around 20GB harddisk space.
I can confirm that current stable boost needs at least >15G free diskspace for the testsuite. Dont remember the exact number.

boost-1.46.1 checks for 15 GB free disk space now.
