OS/2 and eComStation Two articles on OS/2: "IBM's farewell to OS/2 next month shouldn't take anyone by surprise. Long before Big Blue announced its plans to pull the plug, industry watchers were drafting OS/2's obituary." And, "Yesterday saw IBM cease the sale of the OS/2 Operating system. Come the 31st of December, standard support for the OS will end also. However, a significant number of companies and people continue to use it, and they are finding ways for OS/2 to live on."

The SIQ-Problem was mentioned, but delicately left out of the argument by the passionate OS/2-advocates.

In all fairness to the OS/2, the SIQ problem was addressed (through a hacked up fix) as part of W-FP16 (IIRC). The problem was that enabling the fix required editing the config.sys, so most people never enabled it (though I do believe it was enabled by default in Merlin). Even so, all it did was allow automatic focus change away from the offending app (failing to check its input messages) after a couple of hundred milliseconds to prevent the queue from being overrun and it expand the queue depth. The fundamental design flaw of the SIQ was never addressed, but its impact was significantly lessoned.

However, the issue of the shared globally mapped PM subsystem libraries was actually a much more serious problem. Most unrecoverable hangs that occurred were not the result of SIQ (as ctrl+esc would usually get things moving again after a wait), instead they were usually caused by corruption of the UI code itself by an application. I spent more than a few hours with PMDF analyzing system dumps I created trying to figure out why the system had hung. One big offending application turned out to be my favorite (still to this day) word processor, AmiPro (no laughing).

At work, we each get unrecoverable hangs 1-3 times a week on Windows 2000 Pro and have to reboot. The computers are on a network, so we are not allowed to try and fix them. At home my eComStation gets a reboot for a unrecoverable hang 1-3 times a year. This is about the same as my Mac OS X. These are usually caused by going to some web site that is using Windows fluff.

I haven't used AmiPro since I was running OS/2 3.0 . I use WordPro for OS/2 Warp 4 or OperOffice, I have not had either program cause a hang, ever.
