Bug description: php_read does not handle O_NONBLOCK correctly
The php_read function does not seem to handle non-blocking sockets correctly. The read function
will return a negative value when EAGAIN (no data available when in nonblocking mode) error occurs.
(from the man page:
On error, -1 is returned, and errno is set appropriately.) Here is my quick n' dirty patch:
