Perplexing traceback from media-libs/virglrenderer-0.10.1
If the file lock at L1267 of portage/package/ebuild/fetch.py
file_lock = lockfile(myfile_path, wantnewlockfile=1, **lock_kwargs)
fails the user ends up with a perplexing double traceback (attached).
There should be an Exception clause added to the try: that signals
useful information back to the user:
except Exception as e:
"!!! Unable to lock file "
% (str(e), myfile,),

I guess we don't really expect to get a PermissionError when creating a lock file. If that happens, something has probably gone horribly wrong.
The traceback doesn't seem too "perplexing" to me, and would actually be quite useful in debugging an error that should really never happen.
