What the title says.

Priorities:
* figure out how to continue writing pthread_eintr.c so that it works 
regarless of the nr of cores, write as many of function tests as possible
* apply different tools on setuid.c to remove the hang, employ the 
strategy from point one here as well
(in both cases, the program is trying to interrupt a child's function call)
* go through alloc.c again, to hopefully get an idea of why there are 
"unexpected features".

P.S. Attached is my to-report | grep -v musl #because i've recompiled musl
