Summary:
texture number of users increases +1 when material preview render active

Detailed description

Hi,

redo:

add cube
add two materials with the same texture
go to texture panel
set preview to both
change anything so the material preview refreshes

the user count for the texture increases one then goes back down

cheers,

I think it's threading issue. If be more exact -- some kind of data "duplicate" to be thread-safe. Simply, if you'll remove this texture while renderer is active, nothing good will happen.
Ton, you've send much time in making this thread-safe, am i understanding things correct?

Simple fix added in code. Thanks for report!

Sergey: the "nothing good will happen" is not true really, the user counter would be managed perfectly in your example.
