  Log:
  The lock arrays are too small on Windows, leading to buffer overruns
  and crashes when a program opens too many files.
  
  The problem is that on Windows, we shouldn't use FD_SETSIZE to get the
  max number of file descriptors: this is set to 64 in the mingw
  includes.  The real maximum is 2048 (according to the crt sources), so
  we now hardwire that in.
  
  Also, put in a runtime check that we aren't overruning this array.
