searching google results in an article for linux

gives some ideas to work arounds, the most radical to recompile the 
kernel. Then a sysctl -a seems to indicate it is also a kernel 
limitation on FreeBSD:

kern.argmax: 262144

I'm not certain that this is the limit of command line arguments, and I 
  haven't tried to set it. Nor is it clear to me if this is the number 
of arguments or the number of characters in the argument string. In the 
latter case, a "few thousand" argumenst could easily reach that limit.

Cheers, Erik
