[Mono-dev] [PATCH] more support for Google Native Client

Hi there, sorry this is a bit painful, you're really on the bleeding edge
for NaCl and Mono.  Documentation is not great for Mono JIT support in NaCl

If you're running from Chrome (or even sel_ldr) from our Arctic Sea release,
you'll need to set these two environment variables for JIT support:


Changes to NaCl are making their way into Chromium shortly that will take
away the need for these, so if you feel like living on the edge, you could
also get the Chromium sources and build your own version in the next week
that will work without these flags (see chromium.org for instructions). But
there's nothing wrong with using these flags temporarily on your own
