Set address space/files when closing, not writing.
...
This fixes file descriptor leaks. Suppose relibc is just about to set
the address space. For this, it needs to write the address space fd to
the selection fd. To avoid having to close them in the kernel, it rather
memorizes what the file descriptors refer to internally, and then do the
actual operation when they are gone, i.e. when closing.

Multi-core is slightly broken when using the latest version of spin

everywhere, which might have made any possible data race much harder to
come by.
