blocked forever in select() from kwsysProcessWaitForPipe when running under TSan on macOS

I've been working on finding & fixing ITK tests under Thread Sanitizer (TSan). I've tried on 3 Macs:

1. intel macOS 10.14
2. intel macOS 11.6
3. arm64 macos 12.2

On the last one only, many tests block forever with this backtrace:

```

1228 (errno == EINTR)) {

(lldb) p timeout
(kwsysProcessTimeNative *) $0 = NULL
```

As per man page "If timeout is a null pointer, the select blocks indefinitely".

Not sure if it's due to arm64 or due to macOS 12.x. I don' have intel on macOS 12 handy.
