Don't count on that.
Here is a true story (Man - did i had some fun there:)
Once i was hired to QA a delivery (several $M) from a consortium of
Accenture/Microsoft.
One of the task was to control responsetimes for a give number of
simultaneous users. (As defined in the contract).
Did i mention, that delivery was .NET based?
Anyway what *they* did was setting up a testscenario based on MS stresstool
on a Windows PC. MS to MS tool, probably limiting/reusing connections,cache
etc..

What *i* did.
Took my favorite library (Synapse) and wrote my own little 'sucker'.
Simultaneous users and Windows, doesn't really ring a bell, so of course i
used Kylix to write it on Linux.
To simulate real world simultaneous users, every request was with
connection-close.
So what happended? Every once in a while, this .NET thing got fed up with
memory, zombiethreads or whatever, and _had_ to initiate this GC or is it
only G?
The responsetimes for the following requests grew to somewhere between 5 and
10 sec's.
(This was a simple request, and according to the contract it should be below
1. sek).

Here comes the fun part:
They didn't *know* i was doing this backstage, so you can imagine the
meeting where they came with their report, and i came with mine.

..... still laughing slightly evil ....

Oh - did anyone notice the stability of CG's web after migrating to .NET?
