Just a few more comments:
Strangely, PHP_STREAM_OPTION_WRITE_BUFFER also controls the flag
PHP_STREAM_FLAG_NO_BUFFER, which is used only for reading (controls
whether to keep a PHP read buffer or not), which is also a target of
PHP_STREAM_OPTION_READ_BUFFER. So there's already some mixing of read
and write semantics in PHP_STREAM_OPTION_WRITE_BUFFER.
In any case, I still think this should be revisited.

I'm reopening this because the fix makes the meaning of
PHP_STREAM_OPTION_WRITE_BUFFER ambiguous.
For the plain wrapper it's used as a wrapper for setvbuf and the only
values it accepts are 0, 1 and 2, for _IOFBF, _IOLBF and _IONBF.
For the socket stream, it's being used as a synonymous of
PHP_STREAM_OPTION_SET_CHUNK_SIZE. This makes no sense, especially since
the chunk size is also used for read buffering.
I understand the problem, but this can't be the solution; I'm reverting
this patch since setvbuf is specific to the stdio, but not without a
solution first -- perhaps a new function to change the chunk size.
