Comment(by flupzor):

 I'm sorry for my terrible diff. And it seems that i've actually forgotten
 some more fcntl's

 in src/common/util.c in the windows part:
 3967   /* Set stdout/stderr pipes to be non-blocking */
 3968   fcntl(process_handle->stdout_pipe, F_SETFL, O_NONBLOCK);
 3969   fcntl(process_handle->stderr_pipe, F_SETFL, O_NONBLOCK);

 And attached is a diff i wrote earlier for something in
 src/common/compat.c i forgot as well.

 I tried writing a diff for the stuff above but i can't concentrate at all
 at the moment.
