While run my last test code, every time comes one connection, there
are 3 handle leak( I monited it by Process Explorer( from
www.sysinternals.com)), one is the chile process's handle, one is of
"Section	\BaseNamedObjects\cygwin1S5-9770bb4ddbd85dca\cygpid.xxxx",
the other one is of \Device\Afd.
I mean is there any other leak with those handles.
Simple code like the following will not leak anything:
#include <unistd.h>
#include <stdio.h>

int main(void)
{
	pid_t pid =3D fork();
	while(1)
	{
		if ( pid =3D=3D 0 )
		{
			sleep(5);
			printf("Child: %d ended\n", getpid());
			return 0;
		}
		else if ( pid > 0 )
		{
			printf("New process forked.\n");
			sleep(10);
		}
	}
}
