Summary: [GDK]: slow bbp cleanup
Initial Comment:
A few weeks ago i noticed that M5/SQL startup could be very slow.
Probably after a system crash, or quick stop.
I happened to get the same situation and was able to attach gdb.
It turned out that mserver was working in bbpinit/ diskscan
freeing bats. The unlink of a 69 and 111 GB files are
extremely slow. Taking ages.....(many minutes!)
