Under nix, I believe that running like this will result in the kernel
penalising the process by dropping it's priority as it is showing up
as a process hog. This isn't good for LH as it may not get the CPU
cycles when it actually needs them.

Lets not sell the hide until the bear is shoot... Lets worry about
implementation problems once there is a *nix-port to worry about. I think
the graphics/gui will be a bigger problem to port.
Any thoughts about porting the GUI?

Do you have a high-level schematic of the code in design form as it's
really just a coding exercise from that onto another platform or into
a form that would work cross-platform? You have done all the
hard-yards in the design of this and it's that, that takes the most
time and effort.

Actually Heather does not poll the serial port continually. It uses the
Windows interrupt driven serial I/O routines that fill a big buffer in the
background.
What is does do is continually ask give me a serial port character if you have
one. It makes no practical difference

As far as the time slicing goes, the code is continually doing Sleep(0)
calls. These give the time slice back to Windows. You can't get much more
multitask friendly than that.
If Windows has nothing better to do, it gives the time back to Heather

I haven't looked at the source code, but there are other concerns with
the while (true) { checkStuff(); Sleep(0); } approach.
According to the TFM, Sleep(0) is
