# This script is to workaround an apparent LAVA race condition, when it
# detects "EOF" (i.e. app termination) before it reads out all the stdout
# from the app (FVP in this case). The wrapper explicitly runs a command
# in line-buffered mode, that helps a little (LAVA reads more output),
# but not completely, so we just give LAVA more time with some sleep after
# command termination.
