Bug description: Strange freeze when EOF reached in socket.
I'm not sure this bug is related to bug #21529 or not; this is not a
segfault, but a simple program hang. This is from a script I run from a
PHP CLI, and is intermittent. I'd attach the script, but it's a 10k class
file... I've used stream_set_timeout to set the limit to two seconds, and
the connect timeout is also two seconds. From my debugging output, there
are no infinite loops, the freezes are essentially random, and sometimes
nonexistent - but always before a single call to fclose after feof()
returns true. This leads me to believe that a remote server I'm
contacting isn't behaving properly 100% of the time
php -m returns:

I did it three times to make sure, and aside from memory segments, the
trace is the same.
