APR could set sane defaults in autoconf, and the implementation might
vary per-platform (eg. Windows would use/cache the path returned from
the path function).

My main point here is that it is bad to use environment variables
for such things, and it's probably bad to have to run something
every time a temp dir is needed (like check permissions or search
a list of paths and stat() each one). I'd much rather see the apps
leave this decisions up to the users, for example, a simple config
directive in apache.
