Looks like my guess was correct.  I added refence counting to Cygwin's
inaptly-named fhandler structures recently to work around a problem
where a signal handler closed an fd while it was in the middle of a
read.  This caused the memory associated with an fd to be deleted only
when the last thing referencing it was done with it.

The very odd thing was that my implementation seemed to work right from
the beginning.  That has made me wonder what I got wrong.  What I got
wrong was the dup*() family of functions.  If you dup a fd its reference
counter was not reset so the memory associated with it was not deleted.
Duh.

Thanks for confirming.
