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.
