/* The POSIX standard specifies that if close() fails with EINTR the
* file descriptor may or may not be in fact closed. Since another
* thread might have already reused the FD if it was in fact closed
* either a test of FD to ensure that it's closed nor a second
* call to close() may indicate the wrong FD, so the error must be
* ignored.
*
* However, since Mac OS X 10.5 (Leopard) Apple provdes a hidden
* implementation of close that doesn't allow another thread
* to cancel the close so it never fails with EINTR.
*
* The official way to enable this is to set __DARWIN_NON_CANCELABLE
* in the build, but that applies to all system calls, not just
* close(). Following Chromium's example (see
* https://chromium.googlesource.com/chromium/src/base/+/refs/heads/main/mac/close_nocancel.cc )
* we choose to expose and use the hidden close variant only.
