It's also 64-bits on 64-bit platforms, where int is 32-bits and can't
hold as large number as one can allocate consecutive memory regions...

But as you say, the biggest factor is semantics. size_t is size of some
memory region (physical or virtual).

ssize_t is similar, but only used for return results where -1 may be
returned... (signed)

off_t is their cousin, but for positions/ranges in files instead of
memory regions.

In squid-2 we also have squid_off_t which is for object
positions/ranges. In Squid-3 int64_t is used for this purpose.
