Occassionally there are BAD situations where the "dumb" behavior 
amount to system integrity exposures so IBM decides to move ahead
with fixes anyway.  A case in point: a significant interaction between
Websphere and TCP/IP that can exhaust TCP/IP's (and VTAM's) 
alloted allocation of ECSA, and potentially, all of MVS's ECSA.   While 
IBM didn't oper any APARs (as far as I know) there has already been
one fix to Websphere and, according to the grapevine, a TCP/IP fix
and another fix to Websphere in the works.

On the other hand, there was a VTAM perfomance issue that  (I think)
resulted in a PMR being closed as WAD.  So the user submitted
a SHARE Requirement.  The Req was rejected because implementing
the requested function would have left VTAM in violation of APPN
specs.  So the user is left with a significant perfomance problem.  

If both PMRs and Requirements result in no solution, what is next?
How do we bring such things to IBM's attention?
