Summary: changing binaries can cause  oprofiled to abort

Initial Comment:
Some debugging showed we had two different cookies that
pointed to /bin/bash
and that we set up two separate struct sfiles (both
pointing to the same
sample file):

cookie c035e2a0
/var/lib/oprofile/samples/current/{root}//bin/bash/{dep}/{root}//bin/bash/TIMER.0.0.all.all.all

cookie d7bddf20
/var/lib/oprofile/samples/current/{root}//bin/bash/{dep}/{root}//bin/bash/TIMER.0.0.all.all.all

The installed version of bash has an inode number of
1501678:

# ls -li /bin/bash
1501678 -rwxr-xr-x    1 root     root       733508 Feb
23 00:42 /bin/bash

And it turns out not everyone who has /bin/bash open
has that inode:

# cat /proc/8795/maps | grep bash
10000000-100a6000 r-xp 00000000 03:0c 1501678    /bin/bash

# cat /proc/1202/maps | grep bash
10000000-100a6000 r-xp 00000000 03:0c 2187594    /bin/bash

 This is a general problem.
