Interesting... looks like someone's prototype - the return value (the  
process id) isn't even being used.  If we were to use it, we should  
go with getpid().  Thanks for pointing it out, i'll remove it.

We actually have some changes coming that will introduce our own  
gamma distribution (which is the only reason we have a dependency on  
libgsl).  This should make the code much easier to port & install.

Cool, i'll take that change too.  Works ok on opensolaris.

Yeah, this is a known issue we're looking to resolve.  More  
importantly, we're actually looking to change the default way of  
using filebench.  Instead of this interactive mode, i'd encourage  
people to go more of the way of 'runbench'.

I'll look deeper into the code, but offhand, these errors sometimes  
mean you haven't put enough demand on the system.  So try increasing  
'nfiles' from the default of 1000.

Thanks for reporting your issues, and please keep us informed!  I  
really want to see FileBench on linux work really well.
