Re: WDSC lockup (was: Rational Updater)

With all due respect, what you've written shows exactly what the disconnect 
was.  No knowledgeable person would think that an app can block the system UI 
thread (we're not talking OS/2's single kernel msgq after all), so I didn't see 
how what I wrote would be misinterpretted.

The bottom line is that the RSE blocks the WDSC UI thread without the courtesy 
of at least a progress bar with a Cancel button.  It should provide that at the 
very least.  As an Eclipse 3.x plugin, it should also provide a "Run in 
Background" button on said progress bar.  On my previous PC, this behavior had 
more serious consequences than it does on most PCs (I blamed the PC, which is 
why we never opened a PMR on this issue).

We're not having any sort of disconnect.  RSE doesn't "block the UI thread"
on any application other than its own.  In fact, unless I'm grossly
mistaken, there isn't one global UI thread that all programs share; there is
one per application.  That's why one program can lock up and others still
run.

You CAN consume enough resources to make other programs seem sluggish,
especially on an underpowered machine.  This may be what you were
experiencing, I don't know.  But to say that WDSC somehow locks the UI
threads of other applications is imprecise.
