Agreed, but I won't have the time to tackle the process issue
anytime soon. Tim had already removed fixfd, I had to put it back
in for the pipes surrounding the fork() call when I added the async IO
for jthreads, just as you surmised.

I understand what you're saying.
Imagine Kaffe would not use a conservative gc, but a precise gc instead.
