WPF application freezes

[kkokosa]

Steps to reproduce

When typical ClrMd code is used:

use target = DataTarget.LoadCrashDump(@"..\..\..\..\data\ConsoleDump.exe.dmp")
target.SymbolLocator.SymbolPath <- @"SRV*http://msdl.microsoft.com/download/symbols"
target.SymbolLocator.SymbolCache <- @"c:\symbols"
for version in target.ClrVersions do
    let dacInfo = version.DacInfo
    let runtime = version.CreateRuntime()

Actual behavior

Application (WPF) just freezes on line version.CreateRuntime() and becomes completely unresponsive.
