IMO this library has some crucial problems like changing the TPL
during context switching.
For my project "EFIDroid" I've invested many months analyzing, testing
and implementing my own threading implementation based on
LK(LittleKernel, a MIT licensed project) threads and get/set -context.

The result is a pretty stable implementation which can even be used in
UEFI drivers:
https://github.com/efidroid/uefi_edk2packages_EFIDroidLKLPkg/tree/master/UEFIThreads
I'm currently using this lib for my LKL(LinuxKernelLibrary) port to be
able to use linux touchscreen drivers in UEFI - so you could say it
has been well tested.

The only "problem" is that it only supports ARM right now and that the
get/set context implementation was copied (and simplified) from glibc
which means that this part is GPL code.

Thanks
