Keep a rekey out of the mem-IO test harnesses 

Filling the reply queue sends enough to cross a lowered highwater mark.
The rekey that fires sends a KEXINIT the 256-byte mem buffer cannot hold.

- Disable the highwater; a bigger buffer only moves the cliff.
- Both harnesses, since the buffer is the same size on each.
