Thank you Etienne, this is great. I would appreciate you putting up a
wiki page at:


That captures this information and helps folks to collaborate if you
have time. If you need permissions on the wiki space just register for
CWIKI at Apache and tell me your username I¹ll grant you permissions.

As to having a config file in OODT PushPull to set the buffer size,
there isn¹t one (it relies on whatever the underlying operating
system uses - so like you found out if you are on Linux flavors, the
solution you present below is a good way to set this).
