Another crtitical feature is that this call to git-rev-list-like
function MUST be non-blocking.

Reading a big repo could take many seconds, also more then 10 seconds
in cold cache case for Linux tree, as example. Getting the history of
a file ('git rev-list -- /path/to/file) it's also very slow.

There is no way that a GUI tool is allowed to *freeze* for that amount
of time. Currently, because an external process is forked when running
'git rev-list' all the problem is happly handled by the kernel
scheduler and the QProcess callback mechanism (based on select()). In
case of a libified git-rev-list this could be an issue.
