Comment 18 for bug 746822

local test:

=time -v bzr2.4 build project-neon-kdesdk.recipe ./projectneon-build-2 -v
Building tree.
Retrieving 'lp:kdesdk' to put at './projectneon-build-2'.
Retrieving 'lp:~neon/project-neon/kdesdk-ubuntu' to put at
'./projectneon-build-2/debian'.
       Command being timed: "bzr2.4 build project-neon-kdesdk.recipe

       User time (seconds): 0.51

so, the maximum resident memory was 164MB and we should be safe within
the 1GB limit for buildds.
