Thanks for the testcase.  This looks like the new BSD code I added
lately assumes that the datatype time_t is 8 bytes, not 4 byte as on 32
bit Cygwin.  That's just a hunch I take from the fact that your testcase
works fine on 64 bit Cygwin and only hangs on 32 bit Cygwin.  Oh well.
I'll investigate further...
