  Log Message:

  apps/speed.c: Lock buffer in memory

Lock the buffers used for throughput measurements into memory.  This removes
some side effects of paging.

Errors from the memory locking functions are ignored since they are not
critical to the application.

This feature is limited to Linux and Windows.
