Always yield to other greenthreads after database calls
Since common database backends (eg MySQLdb and sqlite) are implemented
in C extensions, eventlet cannot monkey patch the socket calls to ensure
greenthread context switches occur during network I/O.
Previously, this was done by sprinkling explicit greenthread.sleep(0)
calls in areas known to cause problems. Switch that to always do a
yield after execute.
