Actually, this is a kernel limitation. The constant ARG_MAX in your limits.h should tell you how much your own system can take. POSIX requires ARG_MAX to be at least 4,096 bytes.

Not true for your example. the 'for ... in ...' never involves spawning another process that directly reads the entire argument list.

this is because for is a shell builtin.
