Hi all,
from what I gathered so far no emission of write barriers is needed when - running on a uniprocessor (-threaded or not) - running on a multiprocessor sans having linked with -threaded.
On Windows, the non-threaded RTS does I/O with forked threads; see rts/win32/IOManager.c and the async* functions in GHC.Conc.Windows. I think this means that for Windows, we need those write barriers even for non-threaded. -Joey
