<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Example: what happens now when your preferred method is inotify, but it's not available and fam is? If i read it correctly then you end up with neither after your patch. Ouch.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I think you have to change this line to:
if ((!supports_inotify || m_preferredMethod == KDirWatch::FAM) && FAMOpen(&fc) == 0) {
....

even if we aren't going to be using either. This is unnecessary and the
FAM backend has caused it to block for a while on running FAMOpen.</p></pre>
