Oops, this was incorrect. The
weak_counttest handles this, and this change causes it to return EOF when any file descriptor is dropped, if there are several.The real cause of the issue I had was because it failed to set
O_CLOEXECwithfcntl(), which wasn't clear because it didn't make any system call (since that function wasn't implemented in newlib) and git wasn't checking the return value. That is addressed in https://github.com/redox-os/newlib/pull/40.
