+Summary: Runtime ability to disable internal signal handlers
+
+When you're using pinvoke a lot, there are often bugs in either the
+unmanaged code or the managed wrapper that can be hard to track down
+because the runtime overrides a lot of signals, like SIGSEGV, SIGILL,
+SIGBUS, and SIGFPE.  This is especially problematic with gtk#, because if
+there is a bug in code that gets executed from the main loop (like an idle
+function, timeout, etc.) the stack trace you get in managed code is pretty
+worthless because there isn't any stack information from the unmanaged code.
+
+When dealing with bugs like this, an environment variable, like
+MONO_DISABLE_SIGNAL_HANDLERS would be nice so that the runtime would just
+segfault (or whatever).  That way we can use gdb and other tools to attach
+to the process and get a more accurate stack trace to see what's going on.
