035e7913d8 do_fork(): RLIMIT_NPROC check 
1. mcexec sets RLIMIT_NPROC to the number of mcexec threads.
2. do_fork() gets the current number of threads by calling rusage function.
3. do_fork() returns -EAGAIN when the limit is exceeded.

24d8697cef mcexec: workaround for overlayed /sys FS directory lseek() bug 
lseek() on directories under /sys filesystem that are part of an
overlayed filesystem behave differently than in the original /sys.
This causes segfault in libnuma when discovering topology
information. The patch fakes return value as it is supposed to be,
which also fixes the Intel MPI 2017 MPI_Init() crash.
