Is there a way to generate a random number string in b2 ?

I have a rule which may be invoked more than once with the same 
parameters from a jam file. The rule creates build targets based on the 
parameters and I need to give each build target a unique name. Of course 
it would be nice if the end-user invoked the rule with the same 
parameters only once in a jamfile and saved the result in a local 
variable but I cannot force that usage. Therefore I want to generate a 
uniquely named build target even when the parameters to the rule are the 
same. I am using configure.builds with the build target so as long as my 
uniquely named build target matches what is passed to configure.builds I 
am OK.
