There was a discussion recently on Twitter of all places regarding the thread safety of various Cocoa classes. Thread safety includes non-main thread usability, and it was determined that many Cocoa classes aren't safe to use on non-main threads. It's possible that NSWorkspace falls into this category. The solution for NSFileManager was to alloc/init a new one on the thread[1], but I'm not sure if that will work for NSWorkspace. Otherwise you're forced to make all those calls on the main thread. Typically, if a class isn't documented as thread-safe, that implies it is only main-thread safe as well.
