^ Papering over a bug in your code.
Hint: did you tell anyone that you were writing into the buffer?
Ok a write_domain and gem_wait.
gem_wait isn't required, the order is enforced by gem_execbuf followed
by gem_read or subsequent gem_set_domain (if using mmap interface).
The API is geared towards explicit domain management.

at the version I just posted.
Peter.
