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

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

#969 introduced some support for C++ arrays. So far, we know this works for fields of structs. We should add more tests to find out what happens if we allow arrays as actual function parameters, etc. Pretty sure it won't work because the support for arrays in TypeConverter is incomplete. But, we should find out!

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).
