Vadim seemed to think differently:

In addition to Jan's points, using a single pre-allocated file also
reduces file descriptor consumption, although I don't know what the
costs are regarding maintaining the LRU of file descriptors, the price
of opens and closes, the price of having a high upper limit of file
descriptors, etc.
Just because Oracle and MS do something doesn't necessary make it
wrong. :-)
