Hi,

1. unexpected p4 output:

testing with freebsd repository:

vcp cvs:/home/ncvs:src/sys/... --continue \
    map: (...)<> trunk/$1 (...)<(...)> branches/$2/$1 -- \
    p4:/tmp/p4freebsd://depot/freebsd/... --run-p4d

~8000 files, 271015 revs with 240557 tag applications

unexpected stderr from 'p4':

2. cvs continue seems buggy.

testing with the freebsd repository, cvs:/home/ncvs:src/etc/...

vcp cvs:/home/ncvs:src/etc/... --continue \
    map: (...)<> trunk/$1 (...)<(...)> branches/$2/$1 -- \
    p4:/tmp/p4freebsd://depot/freebsd/... --run-p4d

   500 files / 15593 revs

first run finished in about 2 hours. but a consecutive run submitted
another 10 changes. 3rd run ended normally with 'vcp: no revisions to
write'.

3. memory usage

for those interested:

* the ram usage does not grow over 30M while parsing cvs files
  and this takes about 40min.

* the ram usage grows to 60M before it starts writing to p4

* finally, it seems to stay (till it dies) around 90~100M writing to
  perforce.

This actually looks quite pleasant, especially another conversion stays around 15M at the final phase.

But the whole freebsd repository has 55071 files and much more revs, I
wonder the actual amount of memory. I'll post a follow-up when I test
it.

Cheers,
CLK
