[Bf-committers] Using wheels in blender addons

[Bastien Montagne]

Yes, using threading in py scripts in Blender is perfectly valid - as 
long as you do not touch Blender data itself at all (nor try to call 
some operators from a thread, etc.). If you use your own code on your 
own data, no problem with threading at all (i18n messages generation 
script e.g. uses py threads, as well as temp instances of Blender ran in 
background, and so does the batch previews tools generating object 
previews in .blend files).

Cheers,
Bastien
