After an initial glance at this, it looks like this is due to the implementation of FontCache::getFontDataForCharacters for the FreeType backend. It seems be checking if all FontConfig fallbacks contain the characters needed. This requires locking and unlocking each FreeType face for these fallback fonts. Really, we should probably be asking FontConfig directly if it has a good font for these characters.

Likely, once we fix this issue there will be other performance issues with CJK characters we need to tackle as well.
