I did some more reading today and noticed that the NSS documentation (and their sample code for doing crypto without TLS connections) says to use NSS_NoDB_Init to perform a read-only init which don't require a matching close call. Now, the docs aren't terribly clear and also seems to have gone offline from MDN, and skimming the code isn't entirelt self-explanatory, so I may well have missed something. The v24 patchset posted changes to this and at least passes tests with decent performance so it seems worth investigating. > (It looks like the NSS implementation of pgtls_close() needs some thread > support too?)

No idea here, wouldn't that impact pgcrypto as well in that case? -- Daniel Gustafsson https://vmware.com/
