Request for review (S): 7022037: Pause when exiting if a debugger is attached on windows

[Dmitry Samersoff]

Staffan,

Does the method IsDebuggerPresent() distinguish between Visual Studio, 
windbg, cdbg, adplus and so one?

Can we automatically turn this future off when debugging remote JVM or 
windows service?

Can we detect JVM launched by custom launcher (not a java.exe) and turn 
this future off in this case (custom launcher could have no console)?

-Dmitry
