This is probably a naive approach, but is the following code an accurate
representation of how to implement fork() using the Windows 95 RTL C
library?  If so, how much effort would be needed to redo cygwin.dll so as
to make fork() _not_ do anything to the cygwin environment?

#include <stddef.h>
#include <process.h>

void __forker__(void *);
unsigned long fork ()
{
/* Possible code for getting the return address of the fork() caller: */
	return _beginthread((_USERENTRY (*)(void *))forker,
			4096, (void *)NULL);
}

void __forker__ (void *threadno)
{
/* Possible code for inserting the return address of the fork() caller: */
	return 0;
}
