Above you claim to be using svn_wc_status, but your code below is using
You are using the svn API in a horribly inefficient way.
For every file, you are:
1. Locking the WC
2. XML-parsing .svn/entries
3. Getting the status for every item in the directory.
4. Throwing away all but one of the statuses.
5. Unlocking the WC.
So, basically you are doing the amount of work that needs to be done,
As you have found out, 5000 squared is quite a large number.
You should be using svn_wc_adm_open2, then calling svn_wc_status for each
item you want the status of for the operation in progess, then calling
svn_wc_adm_close, OR you should call svn_client_status just *once*, and
fetch the status for each item from the hash you built in the

BAD! Read the API docs for svn_client_create_context()

Also bad. See svn_path_internal_style().

Bad! Didn't destroy the pool!
