heapchk() is just a MSVCRT debugging thing that's not being used. It can be a no-op on Linux. OpenSSL automatically uses /dev/urandom to seed on Linux, so RandAddSeedPerfmon can also be a no-op. Don't let it connect to the network before we've tested it thoroughly off-net. If you have two computers, unplug the internet and use "bitcoin -connect=<ip>" to connect to each other, one windows and one linux. -connect will allow you to connect to non-routable addresses like 192.168.x.x. We don't want to reflect badly on the reliability of the network if it throws off some malformed crud we hadn't thought to check for yet, or discovers something else anti-social to do on the network. I have time that I can do some testing when you've got something buildable to test. I can include it in the stress test I'm currently running on the changes so far. mmalmi@cc.hut.fi wrote:
