Wouldn't this then not accomplish what you wanted initially which was make them
pre-emptible?

Following the LLVM discussion it seems they have decided to leave it as is for
Arm but not revert the Thumb patch that made them pre-emptible.

That seems a bit arbitrary.. 

As far as I can tell the ELF standard says it "can" be pre-empted, not that it
must be.  And with such small ranges is there an actual use case for them to
be?
