++# Allow that 16 coredumps are dispatched in parallel by the kernel. We want to
++# be able to collect process metadata from /proc/%P/ while processing
++# coredumps, and thus need to make sure the crashed processes are not reaped
++# until we finished collecting what we need. The kernel default for this sysctl
++# is "0" which means the kernel doesn't wait for userspace processes to finish
++# processing before reaping the crashed processes — by setting this higher the
++# kernel will delay reaping until we are done, but only for the specified
++# number of crashes in parallel. The value of 16 is chosen to match
++# systemd-coredump.socket's MaxConnections= value.
