Checked in.

Agree with you.
But prec patch have some still hang in there (see
http://sourceware.org/gdb/wiki/ProcessRecord) and this change will be
very big.
If I do it, what I will meet is:
1.  Make a patch follow the hang change, then the new patch cannot
checked in before the hang patch in.
2.  Make a patch just for cvs-head.  After this patch in, this hang
patch need update follow cvs-head.  This is not a small work.

I conflict with them.  So ...

Thanks,
