I've seen similar behavior in my .bash_profile -- one of the last
things it does is invoke "keychain", which almost always winds up
running in the background.  It's true that my .bash_profile starts a
large number of processes, but I don't start any of them in the
background intentionally -- that is, none of the commands in
.bash_profile nor .bashrc end with a single `&'.

I've also occasionally seen commands that I've started by hand at the
command line execute as if they were in the background.  I've never
been able to come up with a simple reliable recipe to reproduce the
problem, though.
