For now this can only sleep in increments of the scheduler quantum (currently 50ms). It also uses a somewhat ineffecient way of tracking the sleeping threads - it will scale linearly with the number of sleeping threads. |

Zion Microkernel
The Zion Microkernel is a capability based kernel. The types of objects that
processes can hold a capability to exist in the object/ directory. The system calls
used to interact with them are enumerated in include/zcall.h and are implemented
in the syscalls/ directory.
The system uses a barebones ELF loader (loader/init_loader.h) to jump to userspace
but from there userspace processes are responsible for loading child processes into
memory and executing them.
