We should add an example that demonstrates how to use a CUDA stream with thrust algorithms, e.g:

thrust::reduce(thrust::device.on(stream), ...);

google/autocxx#929 (comment) gives a good tip for how to explore the generated bindings and should be documented in the manual.

I would like to be able to determine my device-wide primitive's temp_storage_bytes before I have all of the primitive's arguments ready. The interface for obtaining it ostensibly requires everything to be ready for the actual run - and the documentation does not make it clear what arguments it actually needs and what it's going to do with them (e.g. will it look at the input at all, in any way? Pr

Introduced in #128.

The original reason for that is purely technical - it is required to call unshare(CLONE_NEWUSER) in the main thread of a program. Since cachepot-dist is multi-threaded and the build is executed on a new thread, we used a hack in which we fork() and call unshare in the forked child (fork() forks the calling thread into a main thread of a forked child process).
