Description:
------------
Using file_get_contents with an HTTP url causes PHP (CLI, at least) to go into a 100% CPU loop if the connection breaks. Since there's no timeout context parameter, this persists indefinitely.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

I didn't figure an example script would be particularaly useful, as the behaviour described requires the connection to stall or be reset while file_get_contents is running. An example script would simply consist of $data = file_get_contents('http://example.com/a.big.file'); and breaking the connection partway through downloading said file.
