207ec5ce92 core: Enable direct I/O optimistically 
...but keep going if the filesystem does not support it. Fixes Limbo on
older Linux kernels that have io_uring but don't support direct I/O on
all filesystems, such as tmpfs or encryptfs.

so let's switch to them.

fd9af2739e wait for the read completion 
The submit_and_wait command waits for `n` completion events.
We were providing an incorrect argument, which caused the issue.

2684341bac Initial pass on deterministic simulator 
The simulator does not do much, but does discover failures on Linux with
io_uring, though, so it's a start.

84a5115d77 core: Add Windows I/O module 
It's a copy of the synchronous I/O module that we use on Darwin. In the
future, let's switch to Windows IOCP API.

08b40f2af7 core/linux: Move I/O completion to io_uring 
Move the Completion::complete() call to the io_uring machinery. We still
essentially do synchronous I/O because of the call to submit_and_wait()
in pread(), but let's take one step at a time...
