pid_t is not 16-bits, though often the default /proc/sys/kernel/pid_max is set to a value that fits in an unsigned 16-bit number (likely to keep ancient programs working).

The value can be raised to a little more than 4 million, and on most of the systems I influence, this number is raised as otherwise busy systems run out of id's. With the limit set much higher, the chance of pid reuse is lessened, but not eliminated.
