ITS filed for the changes in thread "Thread pool efficiency",
openldap-devel, Feb 2008.
slapd spends too much time contending for ltp_mutex in
the thread pool (libldap_r/tpool.c).
Applying some easy fixes first: Move work out of the region
where pool_submit() and pool_wrapper hold the mutex locked.
Also slapd/result.c checks if the pool is paused every 64
entries and if so returns LDAP_BUSY, it needs no lock for that.
