in thread Linked lists as arrays: inserting values

I should have said heuristics, rather than optimizations. For example, if the point of the next insertion is usually "very close" to the previous insertion, you can make a significant improvement in the performance (e.g. O(n) vs O(n log n)). At any rate, choosing a O(n) algorithm up front instead of a O(n log n) algorithm shouldn't be dismissed as "premature". It could be, in fact, a well-timed optimization of your development process. :-)

We're building the house of the future together.

[tye]: disable /proc and then see what it does?
[davido]: then it reads from /etc/passwd to decide who my uid is.
[davido]: sorry, typed that before you asked me to disable proc
[davido]: but you stumped me; don't know how to disable proc.
[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
davido needs to close laptop to board flight home from yapc.
[davido]: I'll look into it in a few hours probably.
