The comment is still valid, but impact is not so strong.
Key negociations doesn't happen so much during an IPSec tunnel
lifetime, and negociating simultaneous SAs will be slow even with a
multi-threaded implementation if you have a low-end CPU.
And if you have a high-end CPU, SAs will be negociated quickly, then
the impact of negociating simultaneous SAs will be limited.
