FIX: #724 (tee complains if used in a process started by ghc) Now, we only set O_NONBLOCK on file descriptors that we create ourselves. File descriptors that we inherit (stdin, stdout, stderr) are kept in blocking mode. The way we deal with this differs between the threaded and non-threaded runtimes: - with -threaded, we just make a safe foreign call to read(), which may block, but this is ok. - without -threaded, we test the descriptor with select() before attempting any I/O. This isn't completely safe - someone else might read the data between the select() and the read() - but it's a reasonable compromise and doesn't seem to measurably affect performance.
