.SS "Memory management"
During initialization, the pixie attempts to allocate a block of memory
-from the kernel and protect it against being swapped to disk. On most
-systems, this requires that the pixie start with root privileges,
-although it will drop them as soon as it can (before parsing
-command-line options).

+or similar, this should just work assuming that the limit is set
+sensibly. On other systems, this requires that the pixie start with
+root privileges, although it will drop them as soon as it can (before

The locked memory is used for all of the passphrases which the pixie
stores, and for the buffers used to hold requests from clients.
