               Responsiveness of processes executing on normal or low
               priority could suffer due to code purging or literal
               area removal on systems with a huge amount of
               processes. This since during these operations all
               processes on the system were scheduled for execution at
               once.

               This problem has been fixed by introducing a limit on
               outstanding purge and copy literal requests in the
               system. By default this limit is set to twice the
               amount of schedulers on the system. This will ensure
               that schedulers will have enough work scheduled to
               perform these operations as quickly as possible at the
               same time as other work will be interleaved to a much
               higher degree. Performance of these operations will
               however be somewhat degraded due to the overhead of
               enforcing this limit compared to when using a very
               large limit.

               This limit can be set by passing the +zosrl command
               line argument to erl, or by calling
               erlang:system_flag(outstanding_system_requests_limit,
               NewLimit).

 Note! The erts-10.7.2.16 application *cannot* be applied
       independently of other applications on an arbitrary OTP 22
       installation.

       On a full OTP 22 installation, also the following runtime
       dependency has to be satisfied:
       -- kernel-6.5.1 (first satisfied in OTP 22.2)
