One possibility is setproctitle.  It appears to be non-standard, but  
maybe a bit more standard than overwriting argv[0].  I know it works  
on Linux, and I see a FreeBSD man page for it.

"The setproctitle() function is implicitly non-standard.  Other  
methods of
causing the ps(1) command line to change, including copying over the
argv[0] string are also implicitly non-portable.  It is preferable to  
use
an operating system supplied setproctitle() if present."

I do not know whether there is an OCaml function to do this, and it  
might actually be complicated because of the variable length argument  
list.  I have not written enough ocaml -> C bindings to have any idea  
how to handle that.
