[PyCUDA] SCHED_BLOCKING_SYNC query

[Junyi]

For the duration of the kernel call, the cpu busy-waits by default. I
changed the make_context() portion to include the SCHED_BLOCKING_SYNC flag,
but the kernel call just hangs. How should I trigger the release? Thanks!

Can you please supply a) a reproducing snippet of code (ideally short)
and b) some information about your system (GPU, OS, CUDA, Python
versions)?

Thanks!
