Before proposing concrete changes, we would like to know what the general interest is with respect to making LLVM safer in out-of-memory situations. I'm hugely in favor of the general direction. Happy to help by reviewing changes and the like. This type of work was on my long term todo list; I'm thrilled to see someone else doing it now. :) One question: How are you handling EOM?

...rder to write a dataframe on excel. This function creates worksheets using the attribute tablename and writes the data.frame in it. What I want to do is to create this data.frame but being able in case this worksheet already exists to delete the former datas and write the new ones in it. I used the safer and append attributes. When you set safer to false, from what I understood, it should delete the former datas. Then what I did is setting safer as false and append as true so it can append to the empty dataframe the new dataframe but it didn?t work. It appends in the existing worksheets but doesn?...

BTW this causes valgrind to fail in a particularly strange way. I filed a bug upstream with a minimal reproducer.

The network-bridge script is fragile because of how grep is used. As one example, if I already have "xenbridge", I can''t create "xenbr". (It''s actually worse than that, because it''s even grepping the header output by brctl show.) Assuming dom0 is on Linux with /sys mounted (is that a safe assumption?) we can check for the existence of a bridge, and
