IMHO there is no need to have loop like this.
If required, we'd just add -iN parameter to it in the runtest file (where N is
<1,max int), but IMHO it's enough to test host only once.

We need to redirect also second > and &:
EXPECT_PASS host $rhost_addr \>/dev/null 2\>\&1

Also sleep time is not really needed.

Can I merge this simplified variant?

Kind regards,
