Hello,
In recent commit, Eliot merged with .53, but not .54 which adds a disabling module loading.
Please check the http://forum.world.st/Proposal-disable-module-loading-td3396324.html
for discussion.
I will push a new .55 which is merge of oscog.54 and my .54 , so then we could build new VMs with your fixes and disable module loading as well :)
