Subject: Stop using SMX host->data to store MSG host
X-Git-Tag: v3_7~34
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/8d8d6b614e77190ba685eee6fafe653ca0b0eb1e?ds=inline

Stop using SMX host->data to store MSG host

- that's useless since we have the lib to retrieve the MSG_host data
  directly
- it would break java bindings since it stores java object in there

Pretty fucking bug, I've lost my day on this one.
