have keepout areas of the screen and add IMEs to the input, which
would quickly introduce incompatibility with Redox.
Finally, we would like to be able to use stable Rust for our applications,
which we can almost do with Xous. We're just waiting for either the
"alloc_error_handler" attribute to be stabilized (issue 66740), or
defaulting handle_alloc_error to panic (issue 66741), which would give
us everything we'd need to use alloc on stable Rust.
In short, Tock is too small, and Redox is too big.

<h2>Other Alternatives and Inspirations</h2>
<aside class="notes">
There are many alternative operating systems. We can draw inspiration
from them, even if we don't use them directly.
For example, both the QNX microkernel and Solaris Doors implementation
allow for one process to pass a message to another, which then inherits
its remaining quantum and runlevel. This prevents priority inversions
and makes syscalls relatively cheap.
