All:

Perhaps we should clarify the socket tuneables such as:

  ; Default timeout for socket based streams (seconds)
  default_socket_timeout = 60

These are slightly ambiguous.  e.g., we should clarify connect()
timeouts v.s. "idle" timeouts.  

There are at least a dozen tickets open related to timeout behavior and
a lot of the confusion results of ambiguity in the variable naming
convention and documentation.

Anyone that knows the answer to this?

This option sets the default value for the timeout, as though you
manually called stream_set_timeout on the stream.

The behavior is equivalent to using select() to wait for up to the
timeout duration prior to a read or write operation.

PHP does not implement "idle" timeouts; that's an application level behavior.

It should be noted that a timeout in this sense can be a transient
condition in the case of a read operation, it does not necessarily
indicate that the connection is bad, just that no new data is
available within the time allotted.

More general streams bits here that may or may not be apparent from the docs:
