I've recently observerd the same phenomenon.
"ps /l" in DDB revealed 4 lwps stuck in vm_map: xulrunner-bin, ksh,
"bt /a <lwp>" for xulrunner-bin:
"bt /a <lwp>" for the other three lwps looked the same, with "fork1,
sys_fork" instead of the "sys_lwp_create". Unfortunately, I've not
collected the "show uvm", maybe next time.
My environment: i386 with netbsd-5 userland and netbsd-6 MONOLITHIC
kernel updated 2012/02/22, with PAE, 8 GB RAM.
