[SailfishDevel] QML Timer stops running

I case you're interested I've written a QML plugin including libiphb 
(my first attempt was rejected from harbour because I linked dynamically) 
that has the same properties and methods as the Timer component.

In lack of a better name, I named it Insomniac ;)

It's still part of my timer app[1], but I plan to factor it out, clean-up 
code and document it eventually.

An example of it's use can be seen in my main QML file[2].

It's based on libalignedtimer[3], but I've removed any platform specific
code to keep it lean.

I only got it in a working state in the wee hours this morning, so it's by
no means documented and I have to sort out license issues, credits etc.

If you follow the harbour naming scheme it should be an almost drop-in
replacement; all you have to do is change the module name in qmldir and
the PROJECT variable in insomniac.pro.
