Back out the suexec change to mod_rewrite.c. It now builds again.
(No, it wasn't a simple issue to get the suexec patch working.)
The suexec support doesn't apply to the external mapping process,
which is not related to any particular request. Instead, [IMHO]
the external mapping process should switch to the configured user/group
that the daemon processes switch to.
Remove an attempt to fix a race condition. The attempt is not
successful, the race condition is not particularly important (people
deleting users in the middle of a request), and the attempt introduces
more thread-safeness problems. Oh, and I thought I had taken this out
already. :)
A more thorough example is appropriate. Also simplify the behavior and
always return root (/) if n < 1, which is no worse than returning elems
if n > elems.
Add a temporary pool argument to unixd_pre_config, so that it can call
APR functions (grumble). This is needed for apr_stat, which will be in
the suexec path coming up.

Add pool buckets to the bucket list. These buckets are not currently
used although I have begun to test them on my machine. The idea behind
these buckets is that data allocated out of a pool and put into a bucket
has to survive the death of the pool until the bucket is destroyed. To
accomplish this, we register a cleanup when we create the bucket. If the
pool is cleared, the cleanup converts the bucket to a heap bucket and
everything is good. If the pool isn't cleared, then we kill the cleanup
when the bucket is destroyed.
With this bucket type, all of the core buckets that were listed have been
implemented.
