Yes. Now this patch is moot, but if you pass --no-plugins-scan, that is what
Scanning the plugins directories and subdirectories is currently the single
largest bottleneck in libvlc_new(), if the plugins cache is valid. It dwarves
everything else for plugins that are normally already in the cache anyway.
At least on my system (and it´s using an SSD), YMMV. In other words, as long
as we keep this, we can´t speed libvlc_new() up in any meaningful way.
(If the plugins cache is stale or missing, most of the time is loading and
linking the plugins.)
