curl

["Christian T. Steigies" <cts@debian.org>]

Hi,
kullervo was trying to build curl again, and like the previous build, it
timed out in test 518. I tried to renice some processes with htop, but the
test processes were using only very little CPU time. The most time, besides
top, was used by jbd2/dm-4-8, which seems to be related to the ext4 fs. Is
this really slowing down the build? Is there a way to fix this? Do we really
need journalling on a filesystem that is thrown away after every build? Any
tuning ideas? Or maybe curl should skip the tests, as the build itself seems
to work fine?
