+Author: Daniel Drake <d...@laptop.org>
+Date: Fri Nov 25 12:28:48 2011 -0600
+
+ delete_io_handle: fix deletion of last handle
+
+ When num_ios goes from 1 to 0, a realloc(ios, 0); call is made.
+ This is equivalent to free(ios) and NULL is returned.
+
+ However, the previous logic in the code incorrectly discards this NULL
+ return value. When we next call new_io_handle(), realloc(ios, X) is
+ called with "ios" pointing to freed memory. This causes glibc to abort.
+
+ Correct this logic to detect the 1-to-0 case and handle it correctly.
+ Other cases are unchanged; there is still value in checking the
+ return value from realloc() as it also returns NULL on error.
