Andrew:
Currently if we use pygrub --isconfig <image>, there is a good chance
that this command could fail with an "out of memory" error. This can
happen especially if the image file in question is at least a few
gigabytes in size and the dom0_mem setting is relatively small. So even
if any software used this option it is likely it would fail. This
problem is due to the parser using "readlines" function in GrubConf.py,
which attempts to load the entire file into memory.
The advantage of "-l -n" option is that it exercises the "real" code
path, which boots the PV guests.

The pygrub command option "isconfig" is broken and obsolete. This patch removes it since
the alternate options "-l -n" provide the same functionality.
Broken how?
Are you sure that no existing software is using that option?
