Sascha, you are speeding along at an amazing pace on this stuff! Since I don't want to risk you running out of things to do, I have something on my TODO list here that I have been avoiding. ;) It would be extremely handy if the various network-related functions could be timed out on their initial socket connection. Once connected, you can toss the connection into non-blocking mode and timeouts aren't an issue. But you can't do a non-blocking initial connect. The obvious solution is to use an alarm() call and somehow let the user specify a timeout to feed to this call. Then catch SIGALRM. The one slight problem here is that Apache uses SIGALRM and this has been the main reason this hasn't been implemented. Apache 2.0 is unlikely to eat up SIGALRM on us, and after a bit of testing, I think we can actually use SIGALRM even with Apache-1.3.x. It wouldn't be super-safe, and in a worst-case scenario, things might go wrong, but in 99.9% of the cases it should be safe to temporarily grab SIGALRM for the purposes of a connect and then restore the Apache handler afterwards.
