前回まででスレッド対応は完了のはずだったのだけど，ちょっとバグがあったので 修正．
前回のソースコードで info threads を２回実行すると，以下のようになる．
(gdb) info threads

２回目の info threads で，スレッド番号8としてなんかスレッドIDが-1の
stubd というのが出てしまっている．stubd はスレッド番号1ですでに出ているので，
これは明らかにおかしい．

Interface誌の今月号(2007/12)を見ると，HgコマンドがスレッドIDを-1で発行する 際には，どうもすべてのスレッドに対して処理を行う，という意味になるらしい． あと remote.c の内部では，Hgコマンドは set_thread() によって発行されるの だけど，
set_thread (-1, 0);のようにして，スレッドIDを-1として発行している部分がある． まあ上の場合は第２引数がゼロなので，HgではなくHcコマンドが発行されるのだが， スレッドIDが-1というのはやはり特別な意味を持っているらしく， このへんがあやしい．
...とおもっていろいろ調べたり，スレッドIDが-1の場合のqPコマンドやHgコマンドの 動作をいろいろ変えたりして試してみたのだけど，おかしいまま．うーんへんだ．
どうもqPがスレッドIDを-1で発行されること自体，おかしな気がする． それでもってそれがまた成功してしまっているので， その後に Hg も -1 で発行されてしまっているのではなかろうか？
で，スレッド関連の通信内容をもう一度チェック． とくに，多少複雑なプロトコルになっているqLコマンドとかをよく見直す． そしたら以下のあやしい部分を発見．

case 'q':
switch (*ptr++)

int startflag, doneflag, countmax, count = 1, i;

*ptr++ = hexchars[count >> 4];
*ptr++ = hexchars[count & 0xf];
*ptr++ = doneflag ? '1' : '0';
となっており，スレッド数である count が無条件で１になっている．これはまずい．
ということは，qPがスレッドIDを0xffffffff(つまり，-1)で発行されることと， HgがスレッドIDを-1で発行されることの対処を前回入れているが， 実は上記 count がおかしいためにへんなスレッドIDのスレッドが登録されてしまって いるのがそもそもの原因なのではなかろうか？ count に対する修正を入れれば， このへんの対処は不要なのではなかろうか．
で，修正したのがこんな感じ．

今回の修正で，スレッドIDが-1でHgが発行されることは無くなると思われるのだが，
上のほうで書いたように，Interface誌によれば，
スレッドIDが-1でHgコマンドが発行された場合はすべてのスレッドを指す(？)
らしい(？)ので，まあ未対応として「$#00」を返すようにする．
まあたぶん不要だとは思うのだけど，いちおう入れておく．
では動作させてみよう．いつもどおり実行形式を起動して gdb で接続， continue，Ctrl-C でブレークし，info threads を繰り返し実行する．
