> Another question: should we handle EINTR in ioctl() and fcntl()? But this is a different issue.

See attached test stress.py. I tried it with ioctl() and fcntl() implementations of os.set_inheritable() and I got more than 10,000 signals: no syscalls failed with EINTR.

IMHO EINTR is only used when the syscall waits, for example wait for I/O. I don't think that setting FD_CLOEXEC requires any I/O.

Example:

$ ./python stress.py 
got 16871 signals
