Hello all, I really want to support vfork() in klibc, mostly because uClinux *has* to use it. Unfortunately vfork() isn't allowed to use the stack *at all* across the system call -- including return address -- which means it needs an assembly wrapper on most architectures. I have tried implementing wrappers for most architectures, but I don't know parisc or s390/s390x well enough,

If you have access to an Alpha, please test klibc-1.3.21; in particular, anything which uses pipes... Thanks, -hpa

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
