Sorry, you have not made any indication that you didn't want anyone
touching this file.. but I won't put the code in without your ok.
These fields are as they were before.
the code to use them has not been added yet.
I am presuming that the locking for the td versions is the correct
locking for the proc versions. (they will be accessed at basically the
same times) but I'll send you the diffs first so you can check the
locking assumptions. At the moment M:N threads is working except that
there is a gross hack in it to gather all the signals in as they come in
at all the wrong places and redivert them to the right places. Also the
masking for M:N threads is all broken with synchronous signals.
I'm trying to work out how to add code to the system that doesn't break
1:1 threads but does what we need for M:N threads..
As I said.. this commit doesn't touch the fields yet.
I'm just 'reserving them'.

the code when it happens will be reviewed by others, hopefully including
This is just bringing back the presently unused fields. Nothing to
