[Simh] idle feature

[Eric Smith]

Please help - I don't know if I just failed to turn the IDLE feature
on in compilation, or if it's not supported on my Fedora 8
installation.  I did use -lrt to link in the real time library.

--------
[eric at gum BIN]$ ./vax

VAX simulator V3.7-3
sim> show conf
VAX simulator configuration

CPU, idle disabled, 16MB, HALT to SIMH
...
--------

If I try to turn it on (is this how?) I get:

--------
sim> set idle
Non-existent device
--------

Any help would be appreciated!!!
Thanks,
Eric
