Problems closing connections in a SUSPENDED test case

[Artem Grinblat <artemciy@xxxxxxxxx>]

I've come up with an (almost) working SUSPENDED test case:
https://gist.github.com/ArtemGr/9870554

It works in browser and with "curl -v http://127.0.0.1/sustest", at least for some time.

Apache version is 2.4.7 (Debian Jessie).

Problem is, when I test it with ab (ab -n 999 -c 9 http://127.0.0.1/sustest)

it just sits there and then tells me "apr_pollset_poll: The timeout specified has expired (70007)".

I suspect the connections aren't properly released but I don't really know.

Please help me understand what's wrong with the test case.

Am I doing something wrong or is it a bug in Apache?
