John,

Are you willing to test it if I commit changes to CVS to protect all
gdImageStringTTF calls with a lock?  Note that thanks to Dylan we now have
a gd support contract, and if there are any threading issues in gd that people
need fixed we could pursue the issue with the maintainer.   In this case, I
assume the problem is down in the freetype library, so it likely isn't worth
bugging the gd maintainer.

Best regards,
