That's completely true. The whole idea of randomness "wearing out" is

Kaminsky said something very true on Def Con I like to quote a lot:
There are essentially only two problems of random number generation:
a) Early boot time entropy
b) not using a secure rng at all

None of that matters in a normal TLS server setting. (or let's say b
may matter if your software has severe bugs).
