>Description:
mmcformat cannot format a CD-RW very shortly after blanking a CD-RW.
For example, if the mmcformat commands calls for both blanking and
formatting, sudo mmcformat -D -B -O /dev/cd0d, mmcformat fails:

While reading format capabilities : Input/output error

>How-To-Repeat:
Insert a CD-RW into the disk drawer.  Run
sudo mmcformat -D -B -O /dev/cd0d.
>Fix:
A workaround is to run mmcformat -B, wait a while, and then run
mmcformat -O.

For a proper fix, perhaps mmcformat should wait for outstanding
blanking/formatting commands to complete on the drive before either
quitting or starting a new command?
