This was when a child process sent its profile to the parent.
IPC messages are limited to 256MiB: https://searchfox.org/mozilla-central/rev/0d7e190891e62276cf934cc0b96b22e8e086ddb9/ipc/chromium/src/chrome/common/ipc_channel.h#85

Instead of trying to send a too-big message, send a short message starting

Instead of trying to create a too-big shmem, or if the shmem creation fails,
send a short message starting with '*', which the parent can put into the
profileGatheringLog.
Depends on D152027
