--- Comment #3 from Konstantin Belousov <kib at FreeBSD.org> ---
ARG_MAX sizes the exec_map submap, the current formula is 16 *
round_page(PATH_MAX + ARG_MAX).  Increasing ARG_MAX would consume (much) more
KVA on KVA-starved architectures, basically all 32bits, esp. PAE-like configs.

I believe that this was discussed at least once, with Andrey (?).
