7 we cant assume sock_cloexec and pipe2 are bound together as the former defines
8 are found in glibc only while the latter are a combo of kernel headers and
9 glibc. so if we do a runtime detection of SOCK_CLOEXEC, but pipe2() is a stub
10 inside of glibc, we hit a problem. for example:
17 if (!popen("ls", "r"))
21 getgrnam() will detect that the kernel supports SOCK_CLOEXEC and then set both
22 __have_sock_cloexec and __have_pipe2 to true. but if glibc was built against
23 older kernel headers where __NR_pipe2 does not exist, glibc will have a ENOSYS
24 stub for it. so popen() will always fail as glibc assumes pipe2() works.
