Bahadir Balban 05d8438f34 Task initally exec'ing with success. Some errors need to be investigated.

- Directory creation, file read/write is OK.
- Cannot reuse old task's fds. They are not recycled for some reason.
- Problems with fork/clone/exit. They fail for a reason.

lseek
open
close
creat
mkdir

fork
clone
execve
getpid
wait
kill
getenv
setenv


Currently supported functions are:

shmat
shmget
shmdt
mmap
munmap
read
readdir
write
lseek
open
close
