180	Userspace allocator cannot handle big sizes	Jiri Svoboda		"As of revision mainline,236, if I create a disk image on tmpfs, create a FAT filesystem on it, mount it and create a file, it crashes. To reproduce, follow these steps:

{{{
# mkfile --size 2m /scratch/img
# file_bd /scratch/img bd/fdev0
# mkfat bd/fdev0
# mkdir /fat
# mount fat /fat bd/fdev0
# mkfile --size 32k /fat/test
}}}

The command appears to be hung, in klog we can see that {{{Thread 0x80083000 crashed at 0x1af76 (_heap+0x7f76). FP = 0x80028438.}}} The stack trace appears to be bogus:
{{{
  0x80028438: 0x1af76 (_heap+0x7f76)
Warning: udebug_mem_read() failed.
}}}
