Revision 3.420
Add new contributor to list.
Revision 3.421
Bug fix from Alp Aker:
Patch for a minor issue in IOzone's signal_handler() function:
the no_unlink option is respected only for the first member of the dummyfile[]
array; the rest of the dummy files are unconditionally deleted, whether or not
the '+w' flag has been passed to the program.
Revision 3.422
Code cleanup. No functional changes.

Improve consistency of Kbytes instead of kbytes, KBytes, kBytes...

Revision 3.427
Adjust formatting so fields don't run together.
Revision 3.428
Adjust formatting so fields don't run together.
Revision 3.429
Add two more characters to array my_port_num.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
Changes since version 3.397:
Revision 3.408
Bug fix for clobbering of buffer. "tfile" needed to be bigger, as its
address was loaded into filearray[] and then that was overwritten
by the mfflag causing parsed names to get loaded.

Work around for cache_line_size suddenly becoming zero and breaking fetchit()

the proper sharing/dedup within each quadrant, within same seed group
and with previously existing files that were created with a different
number of threads.

Fixes PR 35265, although I did not use the patch provided therein.
* Change the default pattern. Samba is trying to cheat by
special casing IOZONE.tmp, and the pattern of 0xA5.
* Make the default pattern random, and based on Iozone version.
This is to prevent the hack from Richard Sharpe (in Samba)
from special casing Iozone, and lying to the user.
* bug fix in pattern gen.
* Add -+Z old data set mode.
