Has anyone written a Queue.Queue replacement that avoids busy-waiting?
It doesn't matter if it uses os-specific APIs (eg
WaitForMultipleObjects). I did some googling around and haven't found

Because I know someone will ask: no, the busy-waiting hasn't been a
problem in my app. I'm just interested in reading the code.

I wrote a simple, but proprietary queue class that efficiently
enqueues and dequeues arbitrary length byte arrays. I would like to
replace it with an STL container if the performance overhead is not
too high. Currently, I am thinking of replacing it like shown below,
but it is not efficient due to repeated function calls to "push". Can...

I read recently that: "if a before-image was made before an
interruption in database processing, you use the before-image dump &
simply begin processing again from just before the last transaction.
Any checkpoints are irrelevant."
I'm not a dba here, so bear with me... What I don't understand is, why

Hello,
I have a multithreaded windows NT service application (vb.net 2003) that I
am working on (my first one), which reads a message queue and creates
multiple threads to perform the processing for long running reports. When
the processing is complete it uses crystal reports to load a template file,
populate it, and then export it to a...

First off, I am aware that this is a very heavily documented error and I have done my homework for throughly researching probable causes before deciding to post my problem here. At this point, I believe another set of eyes on the issue is merited.

Hi numeric processing fans. I'm pleased to report that you can now have
convenient checkpoint/restart, at least if you are running fedora linux.
Example:
python -i blcr_mod.py <<< this will start python, then checkpoint it
c_int(2) (ignore this debug)
cr_restart checkpoint.nbecker1.23768 <<< this will restart
