Revision: 27856
http://sourceforge.net/p/bibdesk/svn/27856
Author: hofman
Date: 2022-09-06 21:25:50 +0000 (Tue, 06 Sep 2022)
Log Message:
-----------
Don't use DO server to run async thread. Instead run the background thread,
pass messages through performSelector:onThread:withObject:waitUntilDone: and
pass messages to main thread using GCD. Rename classes and ivars, as the object
is not a DO server anymore.
