Here's the exact mmap call...  it's the only one that fails, and it's 
the largest without MAP_NORESERVE.

mmap2(NULL, 209780736, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 
ENOMEM (Cannot allocate memory)

Running the same call from a test program suceeds - I can mmap() things 
that are an order of magnitude larger without problems (as a regular user).
