This bug somehow depends on average length of each argument,
not on the total length of list of arguments.
Big length of each argument triggers the bug for me:
$ cd /
$ find /var/worksrc/netbsd-current/src/sys | xargs echo > /dev/null
xargs: echo: Argument list too long
$ cd /var/worksrc/netbsd-current/src/sys
$ find . | xargs echo > /dev/null
$ find . | wc -c
