+Author: Matthieu Herrb <matthieu.he...@laas.fr>
+Date: Mon Apr 2 08:22:23 2012 +0200
+
+ Fix pci_io_handle allocation routines.
+
+ The previous version of new_io_handle() would invalidate all previous
+ allocations when realloc moves the base pointer of the ios array.
+ Since I cannot figure out where this array is useful, just get rid of
+ it, providing sound stable memory allocation.
+
+ Fixes vgaHWSaveFonts() in 1.12 xserver on OpenBSD, but other
+ sub-systems relaying on pci_io could be affected too.
