Process misattribution in system/socket dataset

Related to a SDH.

Sometimes the TCP connections are assigned an incorrect process, for example `sed` having made a TCP connection.

This was observed in 8.12.2 with debian9, more information on the SDH.

It took me awhile to reproduce but the following works:
In one session:
```
while true;do make clean-all;make -j4;sleep 0.1;done
```
Another:
```
while true; do sudo apt-get -y purge gnome;sudo apt-get -y autoremove;sudo apt-get -y clean;sudo apt-get -y install gnome;done
```

Here we see that one SSH session was incorrectly assigned to `cc`:
