For Red Hat Fedora Core 3, gfortran 4.0.0 doesn't lose output records:
$ ./chk-write-many
uname -a
Linux cerberus.cwmannwn.nowhere 2.6.11-1.14_FC3.stk16 #1 Tue Apr 12 14:39:51 EDT
2005 i686 i686 i386 GNU/L

The test doesn't tell us if the output is correct!
The attached script runs the test but saves the output. On Windows XP Msys
the gfortran output is missing a block of records:
$ ./chk-write-many.sh

Confirmed.
We spend 46.3% of the time in output_float.
8.0% in finalize_transfer.
4.8% in _gfortrani_free_fnodes
4.8% in write_float
Comparing to g77, where we spend:
48.5% in wrt_E
7.4% in wrt_F
7.4% in x_

Same thing on i686:
$ gfortran write-many.f
$ time ./a.out
real0m5.576s
user0m5.508s
sys 0m0.038s
$ g77 write-many.f
$ time ./a.out
real0m3.252s
user0m3.185s
sys 0m0.041s
