为什么程序在运行的时候点关闭按钮没反应，要等到运行完了才能关闭

Public Class Form1

Dim thThread As Threading.Thread

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
thThread.Abort()
End Sub

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
thThread = New Threading.Thread(AddressOf test)
thThread.Start()
End Sub

Sub test()
For i As Integer = 0 To 100000
Debug.WriteLine(i.ToString)
Next
End Sub
End Class
