Apache with mod_neko hangs up on service reload

Clean Ubuntu 18.04 install with Apache 2.4.29 with mod_neko enabled. Using service reload hangs apache so I have to kill -9 it manually:

```
root@Ubuntu-1804-bionic-64-minimal ~ # service apache2 restart
root@Ubuntu-1804-bionic-64-minimal ~ # ps ax| grep apa
10146 ? Ssl 0:00 /usr/sbin/apache2 -k start
10162 ? S 0:00 /usr/sbin/apache2 -k start
10163 ? S 0:00 /usr/sbin/apache2 -k start
10164 ? S 0:00 /usr/sbin/apache2 -k start
10165 ? S 0:00 /usr/sbin/apache2 -k start
10166 ? S 0:00 /usr/sbin/apache2 -k start
10168 pts/0 S+ 0:00 grep --color=auto apa
root@Ubuntu-1804-bionic-64-minimal ~ # service apache2 reload
root@Ubuntu-1804-bionic-64-minimal ~ # ps ax| grep apa
10146 ? Ssl 0:00 /usr/sbin/apache2 -k start
10162 ? Z 0:00 [apache2]
10163 ? Z 0:00 [apache2]
10164 ? Z 0:00 [apache2]
10165 ? Z 0:00 [apache2]
10166 ? Z 0:00 [apache2]
10196 pts/0 S+ 0:00 grep --color=auto apa
root@Ubuntu-1804-bionic-64-minimal ~ # strace -p 10146
strace: Process 10146 attached
futex(0x7f75c6a02214, FUTEX_WAIT_PRIVATE, 4294967277, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x7f75c6a02214, FUTEX_WAIT_PRIVATE, 4294967267, NULL
^Cstrace: Process 10146 detached

```

Removing mod_neko config files allows the Apache to reload correctly.
