372	DosLoadModule kills fork	dmik		"It turns out that if a program loads some kLIBC DLL with DosLoadModule and then calls `fork`, LIBC panics with this:
{{{
LIBC PANIC!!

This happens when the child processes a parent request to duplicate the data segment of such a DLL w/o actually allocating memory for it. The fork child exception handler kicks in with
{{{
