I don't know to be honest. I just run the test and only afterwards check
if it doesn't fail and if the md5sums match:

for i in `seq 4`
do dd if=/dev/zero of=bigfile.$i bs=1024k count=10000
dd if=bigfile.$i of=/dev/null bs=1024k count=10000
done
time md5sum bigfile.*
time rm bigfile.*

I'm not aware of any delay or timeout. Of course the dd output differs
each run.
