[DTrace-devel] [PATCH] test: ensure child processes are running for tst.manypids.sh

[Kris Van Hees]

The tst.manypids.sh test depends on a large amount of child processes
running, and tracing them all.  However, there seems to be a small chance
that one of the child processes isn't completely started by the time the
probes are being created, causing dtrace to fail enabling all probes.

Adding a 1s delay after the child processes are started to give them time
to start completely (i.e. complete the clone and exec using the preload
library).
