True! That was a disaster; only 64K (16 bits) handles were possible across all processes. Many APIs had to be deprecated and redesigned when it went 32-bit.
I've argued for using uuids for handles from here on out. They are endless; no effort to coordinate handle spaces is ever needed; they work locally and on the network; on some architectures they are even a register width scalar.
