Bug description: stream_set_write_buffer() has no effect on socket streams
Description:
------------
Socket streams do not implement the PHP_STREAM_OPTION_WRITE_BUFFER call,
and the stream chunk size is always fixed at 8192 bytes.
This is not a problem with SOCK_STREAM type sockets, but with SOCK_DGRAM
is breaks the datagrams if they are more than 8192 bytes (which is IMHO a
bug).
Here is a patch against 5.3.1 to add support for stream_set_write_buffer()
with socket streams:
