releasing the GIL during init and make_context

by Antoine Martin

Hi, We use pycuda to access NVENC and our application (xpra) if very sensitive to latency, unfortunately it seems that pycuda will hold the GIL during driver.init() and driver.make_context() and those calls can take hundreds of milliseconds to complete. Is there any reason why this is the case? Would you consider a change to pycuda to release the GIL? Thanks, Antoine
