[Bug 394350] Re: RLimitCPU has no effect in Apache

[Kees Cook]

Based on http://httpd.apache.org/docs/2.0/mod/core.html#rlimitcpu I set a 2 second soft and hard limit on the default website /etc/apache2/sites-enabled/000-default:
<VirtualHost *:80>
	ServerAdmin webmaster at localhost
	RLimitCPU 2 2
...

I put the example script above into /usr/lib/cgi-bin/test.cgi, and ran it.  It was correctly killed, observed via strace:
...
[pid 10848] write(1, "2\n", 2)          = 2
[pid 10848] close(1)                    = 0
[pid 10848] munmap(0x7f4f160ed000, 4096) = 0
[pid 10848] close(2)                    = 0
[pid 10848] exit_group(0)               = ?
Process 10848 detached
<... wait4 resumed> [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 10848
--- SIGCHLD (Child exited) @ 0 (0) ---
+++ killed by SIGKILL +++
Process 5234 detached
