Bug description: Using session_start() simultaneous causes script to crash
Description:
------------
I'm experiencing a problem using session_start() simultaneous - ie. in 2
iframes.
An example:
I have a page with to iframes embedded. Frame 1 runs a script with a
while(true), and at line 1 a session_start().
A page is loaded into Frame 2, with session_start() as the only
content. (Except for <?php and ?> of course)
The page in Frame 2 will not be parsed unless the session_start() is
removed
from the top.
It seems as when 2 pages are loaded/loading and executing
session_start() simultaneous, PHP will fail to interpret one of them.
I've tested and determined this issue at two self-contained systems.

Reproduce code:
---------------
I've put up an example:
http://home.madd.dk/phptest/
Expected result:
----------------
I've expected frameA to produce desired output "HEST", but it seems like
frameA.php fails to be parsed.
Actual result:
--------------
See "Expected result"
