[pgpool-committers: 4832] pgpool: Check to see if performance changes according to the nap time t

[Tatsuo Ishii]

Check to see if performance changes according to the nap time to aquire lock.

Change naptime in lock_memcached() from 100 mili sec to 1 micro sec
enhances TPS from 100 to 6900. However, lots of error generated (too
large object).

Also change memcached_erro to memcached_strerror.
