Summary:                    Large Data sent via apr_memcache_set fails due to
nonblocking socket
Description: 
Calling apr_memcache_set with a large data segment returns an error. a data
size of 65535 is big enough for me to cause this to occur.

What appears to be happening is the socket is in nonblocking mode because
apr_socket_timeout_set() is set (as I understand it via apr
documentation). Later when the data is sent, apr_socket_sendv() returns
success, but the number of bytes written does not match the number of
bytes sent (this is normal for a nonblocking socket). The desired response
is for the consumer of apr_socket_sendv() to resend the remaining data.

I have supplied a patch that fixes this issue, it applies to release
0.7.0, but should also apply to the current trunk. I am not a regular apr
consumer so I'm not sure if this is how they intended it to be handled,
but the approach I am providing is straight forward and works.
