[Mono-list] Handle daemon?

[Simon Ask Ulsnes]

My CFLAGS weren't extreme, only -march=pentium4 -O2 
-fomit-frame-pointers and -fprefetch-loop-arrays.

I noticed something peculiar: It doesn't happen when running mono as 
root. Does the handle daemon require access to some specific part of my 
system? When I run Mono as root, all is good. Maybe this is kernel related?

I can also set the environment variable MONO_DISABLE_SHM=1, but that 
causes MonoDevelop and other apps to randomly segfault.

Thanks for helping...

Yours,
Simon
