 If you could tell us for which fd that ioctl is failing, and what the
errno is, that would be great.  Also, does NT define O_ASYNC?  If so,
then there's probably no need to call FIOASYNC if the fcntl(O_ASYNC)

You mean with debug?

Seem like you're running out of memory.  A good point to look is
gc_system_alloc in gc-mem.c.  You might also want to check in config.h
which of the alternatives that gc-mem.c tries are available under NT.
