BAKRs do not create or cancel ESTAEs.
PRs do automagically cancel all ESTAEs created since the matching
BAKR. There is a bit (in the BAKR's stack entry I think. I forget
which and where.) that, when set on, causes an interrupt to occur
when the PR is issued. This is how z/OS gains control so that it can
do the purge of the appropriate SCB[s].
I remember how surprised I was to discover this some years ago when I
was writing z/XDC's linkage stack support.

Hi
I thought for the longest time that an ESTAE was associated with a Task.
Then I saw a thread with Chris Blaicher where the upshot as that a BAKR
would deactivate it
I did a search on the archives but didn't come up with anything.
