When running out of memory, Performer calls

    pfNotify(PFNFY_FATAL, PFNFY_RESOURCE, ...

The default pfNotify handler exits on PFNFY_FATAL. You can replace it with
a more mellow handler (man pfNotifyHandler). You can then take the required
action before calling exit or return normally and expect NULL as the pfMalloc
result.
