We shouldn't be using synch reset (even though Xilinx recommends
otherwise and Altera gives mixed recommendations), for the reasons you
stated. I thought I had changed to asynch reset.

I've checked and updated a few (sha-1, sha-256, coretest, uart). Now all
main cores are using asynch reset. Thanks for pointing this out.
