How much of a thread's memory is kept alive - after the
thread has terminated - as long as a program holds on to the
thread's `ThreadId'? The following ToDo comment in
`PrelConc' seems to indicate that it is currently more than
we really want:
data ThreadId = ThreadId ThreadId#
-- ToDo: data ThreadId = ThreadId (Weak ThreadId#)
-- But since ThreadId# is unlifted, the Weak type must use open
-- type variables.
In combination with finalisers, this can be troublesome.
