When merging several large packages in parallel, it's sometimes not possible to interrupt emerge with CTRL+C.
The output looks like this:
>>> Emerging binary (45 of 192) sys-devel/gcc-4.6.3
>>> Emerging binary (46 of 192) dev-util/pkgconfig-0.27
>>> Emerging binary (47 of 192) net-misc/curl-7.26.0
>>> Jobs: 44 of 192 complete, 3 running Load avg: 1.22, 1.68, 1.52^C
Exiting on signal 2
>>> Failed to emerge sys-devel/gcc-4.6.3, Log file:
>>> Jobs: 44 of 192 complete, 2 running, 1 failed Load avg: 1.22, 1.68, 1.52^C^C^C^C^C^C
gcc failed because I pressed CTRL+C, but the others continue and are not interruptible. The log file it mentions does not exist.
# emerge --version
