4G of ram not enough? That would be interesting if its not.

No, i dont like workarounds because when i report bugs i try to put 
myself in the position of new user. If substitutes are essentials for 
users then it should be enabled by default , or switched automatically 
if there is something bad happened like this issue. And if its not then 
the default configurations has something need to be fixed/improved to 
avoid issues like the one i have reported.
