Subject: Dynamic linking in the kernel

Hi folks,

just some naive thoughts on dynamic linking:

Starting up an dynamically linked executable tends to need a lot
of syscalls. A kernel-based dynamic linker could cache a lot of
relocation data (eg. when the same binary is called many times),
share pages even w/o mmap(), and the ldstub wouldnt be needed
anymore.

At that point we maybe also could create a new binfmt which is
tailored to efficiency (much simpler than ELF)


What do you think about this idea ?
