That does not necessarily create parallel instances.  If the operation can
be completed in a single context switch (and it most likely can), then
while you are creating 20 separate threads, they are still done in
sequence.  You'll need to use condition variables to pause all threads
until all are started, and a pthread_cond_broadcast after all are started,
and sched_yield() within each thread at various intervals to correctly
simulate parallel queries.
