Does TLS periodically require some potentially expensive cryptographic
operation such as generating a new key? Perhaps there is a difference
in the period specification for MBEDTLS vs WolfSSL.
There are relatively expensive operations done when the connection is
established; those don't seem to cause WDT or queue overflow. So if
there is a periodic expensive operation, the problem must be that
doing it in the midst of some other operation causes the problem.
