Increasing scan rate to 10 kHz

[Evgeniy <tikh@triumf.ca>]

Hello,

I can easily set scan period to 0.01 second by adding:

choice(menuScan_01_second,".01 second")

in dbd file.

What about adding scan period 0.0001 second?
Similar line:

choice(menuScan_0001_second,".0001 second")

doesn't work.

CLOCKS_PER_SECOND on my 8-core DELL server is 1000000 (running SL5.4).

What should I do to set scan period to 0.0001 second?

I need such short period to quickly fill in the circular buffer of 
compress record.
Thanks,
Evgeniy
