Description
I get rendering errors and sometimes exceptions in my regression tests. It is somehow related to several threads initializing standard 14 fonts. It happens only about every 25 times in a test program I created. That one renders 2 files in 4 threads and compares the result with the existing result.
My theory is that one thread accesses the naming table and another accesses the glyf table, and both change the stream position. I tried several things in the last months to avoid it, all were unsuccessful and I lost my notes about it last winter due to a static discharge on a usb stick. (Thank you KINGSTON!)
Here's the output when it doesn't go well:

Sometimes in the past I got exceptions:
