--- Comment #88 from Zhiyi Zhang zzhang@codeweavers.com --- (In reply to Kimball from comment #86)
The new implementation does seem to reliably work for me, including re-installing battle.net (although admittedly I hadn't done a fresh prefix). I do however have a few other changes of things I haven't decided are important - I am noticing that there seems to be a whole slew of sub-processes (or perhaps threads?)
It's possible that with a working PAGE_WRITECOPY support, some processes that were previously crashing can now go further.
