  他只是系統 per-process limit 的限制。

<quote from /usr/src/sys/conf/NOTES>
# FreeBSD processes are subject to certain limits to their consumption
# of system resources.  See getrlimit(2) for more details.  Each     
# resource limit has two values, a "soft" limit and a "hard" limit.
# The soft limits can be modified during normal system operation, but
# the hard limits are set at boot time.  Their default values are
# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
#                                                                    
# 1.  Set the values at kernel build time.  The options below are one
#     way to allow that limit to grow to 1GB.  They can be increased
#     further by changing the parameters:                          
#                                       
# 2.  In /boot/loader.conf, set the tunables kern.maxswzone,
#     kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
#     kern.dflssiz, kern.maxssiz and kern.sgrowsiz.           
#                                                 
# The options in /boot/loader.conf override anything in the kernel
# configuration file.  See the function init_param1 in           
# sys/kern/subr_param.c for more details.

  好像 init_param1() 的東東是不屬 sysctl 管的。可以由 ulimit -a
  得知。                                                      


ps.像我編字型，一個 Unicode 字型那麼大，使用 fontforge，不把 maxdsiz
   增加，根本就沒辦法用。
