Advantage: Less memory used (each thread needs a block of memory in the kernel,
I'm at work & can't remember the struct name off hand). In the case under
discussion, this doesn't make much difference, but in a large project, memory
use can become critical.
Disadvantage: cannot set the priority of main(), except by re-compiling kernel,
AFAIK.
