another gpus_ReturnNotPermittedKillClient crash

[ghost]

We are using the latest commit of XBPageCurl in our project. We did add Crashlytics recently and that might or might not be contributing. This occurred from one of our testers and we are unsure on how to reproduce, but were hoping you might have some info here, or maybe this trace can give some clue as to whether it is an XBPageCurl bug or not? Thanks.

The trace below was provided from our iOS dev, from Crashlytics:

Hello, have you resolved this issue? I have the same problem. Thanks a lot.

[xissburg]

I didn't look into this again yet. I have seen this problem before and after searching around the web a bit I found that could be a problem with OpenGL commands being called while the application is not active, on the foreground. I have written some code to make sure all OpenGL operations would be completed before the app goes to the background, but it seems it wasn't enough... I have not being putting effort into developing this project lately, because I've been busy and not motivated.
