This patch set is better, userspace seems more stable but I am still
seeing some odd problems. This is from straceing mount, which displays
nothing even though /proc/mounts shows everything mounted properly:

open("/proc/mounts", O_RDONLY)          = 3
fstat64(0x3, 0x7fe7e2a8)                = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x3001f000
read(3, 0x3001f000, 1024)               = -1 EFAULT (Bad address)
exit_group(0)                           = ?

it looks like the memory allocated using mmap is bad?

take care!
