SubjectRe: Linux 2.3.39 has 32bit uid. What about 32bit pid?

Glibc pid_t is 32 bits on i386:
typedef int __pid_t; /* Type of process identifications. */

The IPC stuff is special-cased:
/* Used in `struct shmid_ds'. */
typedef unsigned short int __ipc_pid_t;

I am on for increasing pid_t size simply because 32000 processes may
become a bottleneck on large servers. The restriction isn't necessary
any more. `top' will be pretty slow though.
