+# Hi,
+# 
+# A Debian user reported[0] gawk 3.1.4 broke a (relatively) complex
+# program that makes extensive use of awk, called 'apt-move'.  I finally
+# managed to reduced the problem down to a 3 line test case, enclosed
+# below[1].
+# 
+# I believe the problem comes from the following code, introduced in
+# 3.1.4:
+# 
+# [io.c, line 560]
+# | 	for (rp = red_head; rp != NULL; rp = rp->next) {
+# | 		if ((rp->flag & RED_EOF) && tree->type == Node_redirect_pipein) {
+# | 			if (rp->pid != -1)
+# | 				wait_any(0);
+# | 		}
+# 
+# The problem is that, if we have an existing redirect which is a simple
+# file redirect[b] and it's hit EOF and we try to create a new '|'
+# redirect[c], this new code will try to wait(2) and if there are any
+# other redirects which _did_ spawn a child (like [a]) the wait() will
+# hang indefinitely waiting for it to exit.
+# 
+# Hope that makes sense :)
