// 注意:異なるスレッドが所有する VCL のメソッド/関数/プロパティを
// 別のスレッドの中から扱う場合,排他処理の問題が発生します。
//
// メインスレッドの所有するオブジェクトに対しては Synchronize
// メソッドを使う事ができます。他のオブジェクトを参照するため
// のメソッドをスレッドクラスに追加し,Synchronize メソッドの
// 引数として渡します。
//
// たとえば UpdateCaption を以下のように定義し、
//
// void __fastcall Unit1::UpdateCaption()
// {
// Form1->Caption = "スレッドから書き換えました";
// }
//
// Execute メソッドの中で Synchronize メソッドに渡すことでメイ
// ンスレッドが所有する Form1 の Caption プロパティを安全に変
// 更できます。
//
// Synchronize(UpdateCaption);
