rather than the `ln` hack (which requires $BASHPID which is in bash-4.0+), it should simply use `flock`

(
flock -x 9 || die
... do stuff that needs the lock
) 9>/path/to/common/lock/file

bonus: this won't burn the cpu

We should probably go for a locking helper in eutils that has cases for multiple OS-es.

(git-r3 no longer needs locking)

Locking is no longer used in the eclass.
