  An INQUIRE against a running/suspended task ( Task_A )
  returned various parameters of Task_A including its PROFILE
  ( Profile_A ). In doing so, CICS INQUIRE code obtained ( but did
  not release ) a READ lock against Profile_A's definition.
                                                                 .
  Task_A ended but with the INQUIRE task either running or
  suspended, an attempt to re-install Profile_A failed with
  message DFHAM4841 being issued and indicating that:
                                                                 .
  " An attempt was made to install object definition restype
  resname on the CICS system, but the installation failed because
  a read lock was held on that definition by task taskno. "
                                                                 .
  In this scenario, it was unnecessary for the INQUIRE code to
  retain a READ lock against Profile_A.
                                                                 .

  in the aforementioned scenario.
