  Log:
  MAXPATHLEN is 1024, which means NdisOpenFile() and ndis_find_sym() were
  both consuming 1K of stack space. This is unfriendly. Allocate the buffers
  off the heap instead. It's a little slower, but these aren't performance
  critical routines.
  
  Also, add a spinlock to NdisAllocatePacketPool(), NdisAllocatePacket(),
  NdisFreePacketPool() and NdisFreePacket(). The pool is maintained as a
  linked list. I don't know for a fact that it can be corrupted, but why
  take chances.
