"nio" branch

[Phil Norman]

Hi.

I did some work a while ago, converting Evergreen (and to some extent Terminator) to use NIO, rather than the original java IO package. Side effects include better support for symlinks, faster file access, and more efficient updating of the file lists and 'find in files' results.

I've been using it without trouble at work since then, and haven't found any problems with the current version. It's quite a large change, though, so if someone would like to take a look, I think that'd be good.

If no one feels the need to take a look, though, I'd quite like to merge back into the main branch, as otherwise things are eventually going to start diverging in ugly ways.

Cheers,

Phil

Hi again.

I've merged 'nio' back into the main branch. Thanks very much to ritschwumm for the useful review comments.

It's quite a big change, so if you have local evergreen/salma changes, please merge with care. As I mentioned before, I've been running this at work for some time now, and haven't had any issues.

Cheers,

Phil
