Comment:

 At first glance, it looked like this was doable by calling
 SSL_ConfigServerSessionIDCache() during nsNSSComponent::InitializeNSS().
 However, the system appears to be written to use a default session ID
 cache size if you set it to 0.

 There does appear to be an SSL_NO_CACHE option that can be set with
 SSL_OptionSet(), as well as an ssl_defaults that we can bang on to disable
 session ID caching for each individual ssl socket.

 I am going to try that and see what happens.
