Looking at Apache or Samba projects, it seems that a good compromise is to
set a 'maximum client requests by thread' and spawns threads accordingly.
Apache uses process forking and memory sharing, but the design remains the
same. You then just tune this max_request_by_thread for each OS, say 1 for
Solaris which is said thread-efficient, 10 for Linux ? Just a hint ...
