That is very strange and I have not had that problem.

This sounds like you are not properly handling the stored objects. I use a single status pipe, where a child reports some identifier and an indication that a binary object is available, and a "return" pipe for each child, where the Storable data is actually written. The status pipe is non-blocking and monitored with Tk's fileevent mechanism, while the "return" pipes are used in blocking mode. I switched to this approach after trying to pass the Storable data back on the status pipe and finding that non-blocking mode caused problems, not to mention that the status pipe is shared, so the messages returned on it must be kept short enough to fit in the OS buffers to avoid messages from different children being interleaved.
