[fpc-pascal] Better random numbers ?

Hi, I am using standard run of the mill randomize/random() calls in a program
to generate random numbers, used in turn to select random data which is fed
into another program.
(All this just to create a multi-language enabled module structure eh)
Well there is just one little problem, on the commandline it works fine, just
about every single call gives a different result, or different enough.
But when run from inside my other app (where it is threaded) and where I
cannot proceed until I have at least the first 5 non-repeating values, it
doesn't work so great, I have to call the program an average of 40 times
before the value changes - I presume because randomize gets it's seed from
the clock and that is how long it takes for the whichever value it uses to
So is there a better way I can do this ? Some way of getting a more frequently
updated random seed ? I am talking literally every few milliseconds here.
