[Octave-bug-tracker] [bug #57439] handles to private functions may fail after "clear functions"

[Markus Mützel]

Follow-up Comment #50, bug #57439 (project octave):

Using "stat" to determine if a file exists is about 30 times slower than using
"GetFileAttributesW" on Windows. That is 3000%!

I used the attached .oct file functions for the test. Running "file_exists"
which loops 1e6 times took 5.4038 seconds. "file_stat_exists" which loops 1e4
times took 1.54844 seconds.

Even if this won't be the real fix. There is definitely room for performance
improvement.
