Comment (by AGMS):
Replying to [comment:3 korli]:
I failed to reproduce on hrev50773 x86_64, qemu 2CPUs 10 parallel tests
(system() and load_image()), 1000 runs.
You're right, I couldn't get it to happen in x86_64 either. Though the
forking/execute program speed is slow, over 10 minutes, with 10 windows
open, got up to 8000ish iterations, so that's 80000 forks in 10 minutes or
8000 forks per minute or 133 forks per second.
With 32 bit Haiku, it's a bit faster (10000 interations in 10 minutes, or
166 forks per second), until it stops working (first one cut out at just
over 5000 iterations on a bare hardware test, hrev50765, Intel 4820K i7 4
core CPU at 3.7Ghz).
And with a recent Linux on the same hardware, it zips along at 9000 forks
per second.
