In Delphi 2007 TThread.Create specifies the standard thread stack size passing 0 for the dwStackSize parameter.

  FHandle := BeginThread(nil, 0, @ThreadProc, Pointer(Self), CREATE_SUSPENDED, FThreadID);

An overloaded constructor that could set per-thread stack size would be welcome.
Steps to Reproduce:
See description.

As concurrent programming (and increased number of threads) is getting more and more important, customizing a threads stack size becomes a necessity.

PLEASE PLEASE fix this extremely serious bug.  In applications which require a large stack size for their main thread (in our case due to legacy code making extensive use of recursive procedures) it is extremely serious that every single thread must also have large stack.  I can (laboriously) fix this for my own threads, but with more and more code (Parallel Library for example) using standard TThread code, the existing code is insupportable.

We really would also like some sort of global default stack size for threads other than the main thread (obviously separate from the windows one stored in the executable).
