Why are ``all things embedded'' suffering?

I know of two cases:

a) The threads have a 100% shared address space.  Binding memory 
accesses to a thread will make zero difference.

b) The threads do not have a 100% shared address space.  Binding memory 
accesses to a thread will at least make it better reflect GDB's view of 
a threads address space.
