# The following two tests try to ensure a limited window size means
# limited memory allocation. They don't work very well. The virtual
# address space rlimit (ulimit -v, RLIMIT_AS) must cover the stack size
# that is allocated automatically for the process, which varies from
# machine architecture to machine architecture (the kernel's MAXSSIZ
# parameter), as well as any shared libraries that get loaded in and
# other auxiliary crud the loader or libc might allocate.
#
# In principle, the overhead from that and the program image should be
# constant, and the only substantial memory allocation performed by
# vndcompress should be w*8 bytes or (n/b)*8, where w is the window
# size if specified, n is the size of the input, and b is the block
# size.
#
# We could perhaps do an exponential growth and then binary search on
# the virtual address space limit to determine the overhead, but that's
# more trouble than I care to do in a makefile right now. Currently
# this is calibrated for NetBSD/amd64 6, where 128 MB of virtual
# address space is allocated for the stack. (Note `ulimit -v' takes a
# number of kilobytes, not a number of bytes.) Since this is not
# reliable, however, these are commented out.
