I'm sorry to be pedantic but could you please move the static variables in
GpuProcessHost::~GpuProcessHost into static class members and provide a static
method to query the gpu_crash_count? This should get the crash count from the
GpuProcessHost instead of keeping its own copy. Also, this should be moved up
one line. At this point the GpuDataManagerImpl can't be accessed in a thread
safe manner. (The above object is an "unlocker", not a locker.)

Done.
