Sorry, overlooked this one. Patch looks sane, but needs to be adjusted to the current master. I'll do that, run some tests and - if successful - send an updated patch to the mailinglist.
Edit: I'll do this somewhere in the coming days.

"Coming days" became "coming weeks", but finally the patch has been applied to master, and will be included in OpenVPN 2.4.

OpenSSL indeed seems to eat a lot more money than PolarSSL.
Syzzer, can I interest you in this one...?
(As it's a "new feature, no bugfix, no long-term compatibility thing" it won't go into 2.3, but if we can save on memory for 2.4 without losing functionality, all for it)
