# We want to verify that -j 2 starts precisely two jobs, the first of

# which fails and the second of which succeeds, and then stops processing
|

# due to the first build failure - the second build job does not just
|
|
# continue processing tasks. To try to control the timing, the two
|
|
# task scripts will be managed by a server script which regulates the
|
|
# state of the test.
|
|
#
|
|
# The failure script waits until the server responds that the
|
|
# copy script has, in fact, gotten started. If we don't wait, then SCons
|
|
# could detect our script failure early (typically if a high system load
|
|
# happens to delay SCons' ability to start the next script) and then not
|
|
# start the successful script at all.
|
|
#
|
|
# The successful script waits until the server responds that the
|
|
# failure script has finished (the server checks that the task pid does not
|
|
# exist). If we don't wait for that, then SCons could detect our successful
|
|
# exit first (typically if a high system load happens to delay the failure
|
|
# script) and start another job before it sees the failure from the first
|
|
# script.
|

# Both scripts are set to bail if they had to wait too long for what
|
