+ <item>Lock physical memory. The default value is <c>no</c>, i.e.,
+ no physical memory will be locked. If set to <c>all</c>, all
+ memory mappings made by the runtime system, will be locked into
+ physical memory. If set to <c>all</c>, the runtime system will fail
+ to start if this feature is not supported, the user has not got enough
+ privileges, or the user is not allowed to lock enough physical memory.
+ The runtime system will also fail with an out of memory condition
+ if the user limit on the amount of locked memory is reached.
