<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I wouldn't use key() for that, as there is no guarantee AFAIK that if not found, it would return 0 (it usually returns a default constructed key, which in case of an int could be pretty much any value.).
As such, I either propose .key(service, 0), which guarantees the returned key would be 0 if not existent; or .values().contains(service). I'd choose the second for clarity.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I did worry about that, but according to http://qt-project.org/doc/qt-4.8/containers.html#default-constructed-values it's safe:
"But for primitive types like int and double, as well as for pointer types, the C++ language doesn't specify any initialization; in those cases, Qt's containers automatically initialize the value to 0."</pre>

Remove inhibition with take() for efficiency
