I don't think anything but I have to verify this.  The code causing
this behaviour was introduced because of a POSIX conformance
test. This required that it is possible to interrupt a blocking fwrite
using a signal (e.g., SIGALRM).

I'll have to look at this in more detail and therefore haven"t
responded so far.
