You might want to throttle the number of outstanding promises.<BR>
If only Posix provided good functions for e.g. finding the number of processors.<BR>
Or if NT or Posix made it easy to discover the number of spindles backing a path,<BR>
or to easily measure system utilization and backing down when it gets near 100%.<BR>
You know, an idle machine should be maxed out, but no more.<BR>
A machine with an interactive user should reserve CPU/memory/I/O for forground activity..<BR>
I don't I've ever seen this stuff done well though.<BR>

The vast majority of the runtime of the compilation of a typical Modula-3 program is spent in the part "promised" here (when using the GCC backend).<BR>> <BR> </body>
