* show resources in task details
* fix task state locking
* return task object consistently
Race condition iexisted where task State, err, and processReturnValue fields
were written by consumer goroutine and read by concurrent accessors without
proper synchronization, causing torn reads and data races.
This commit blocks concurrent calls to RunTaskInBackground which is
intended to fix the quirky behaviour where concurrent PUT calls to
api/publish/<prefix>/<distribution> would immedietly reuturn an error.
The solution proposed in this commit is not elegant and probaly has
unintended side-effects. The intention of this commit is to highlight
the area that actually needs to be addressed.
Ideally this patch is amended or dropped entierly in favor of a better
fixup.
