I recently experienced the following situation.  I have 3 background jobs,
all interactive shells, nicely arranged as job #1, job #2, and job #3.

When I do the "j" command ("j" is aliased to "jobs -l"), I get something
like:

[1]+ <number> Running         ssh somesystem &
[2]  <number> Running         ssh someOthersystem &
[3]  <number> Running         sudo bash &

Now, I did %1 and (accidentally) logged out of somesystem.  Now, when I do
"j", I get:

[2]  <number> Running         ssh someOthersystem &
[3]  <number> Running         sudo bash &

So, I ssh back into somesystem and do the usual ~^Z and find that it is now
job #4.  I want it to be job #1, like it was before.

Now, usually, when something like this happens, it is because some file or
some other resource is still open on the old object, so it cannot be
recycled.  But this doesn't seem to be the case here.  I tried it a few
times, but could not get back the #1 slot.

Eventually, I exited jobs 2 & 3, and then re-launched ssh somesystem and it
came out as job #1, after which I was able to re-construct jobs 2 & 3 and
then things were as they should be.  But should this hack be necessary?
