While debugging something for Borderlands 2, I broke the DRI driver, tripped a
file descriptor leak

Mesa git master (Sept 10th build), kernel 4.3.0-0.rc0.git9.2.fc24.x86_64m
libdrm-2.4.64 aug 18th

Steps to reproduce fd leak
==========================

Take my trace for Borderlands 2 from here:
https://drive.google.com/open?id=0Bze7CJKD12nORWQ4RTdIbk4zT1k

1) apitrace trim --frames=0-2469 --exact -o bl2469.trace
Borderlands2-menu.trace
2) apitrace replay --loop -b bl2469.trace

Wait... it will crash... see attachment
