DynamicVariables are stored in the env variable of Process, the stack
doesn't store this information, so if you're about to serialize a state of
a Process, then you have to serialize the env variable too, otherwise
you'll lose information.

Hi Sean. I am still seing the problem :(
It is difficult to make it YOU to reproduce it, but it is easy that tomorrow
I show it to you :)
Basically, what is happening is that
ZnClient >> executeRequestResponse
self logRequest.
ZnSignalProgress enabled ifTrue: [ HTTPProgress signal: 'Writing request' ].
request writeOn: connection.
connection flush.
ZnSignalProgress enabled ifTrue: [ HTTPProgress signal: 'Reading response'
].
response := request method = #HEAD
ifTrue: [ ZnResponse readHeaderFrom: connection ]
ifFalse: [
self streaming
ifTrue: [ ZnResponse readStreamingFrom: connection ]
ifFalse: [ ZnResponse readFrom: connection ] ].
self logResponse
throws a mustBeBoolean in the first line "ZnSignalProgress enabled ". It
seems that such expression answered the SmallINteger 30 the first time.
If I take the debugger and I evaluate ZnSignalProgress enabled again, it
answers me false, which is the correct value.
Ahh yes, this in latest 2.0.
I would have expected a ZnSignalProgress class >> default saying "^
true" (or something else of a Boolean nature). DynamicVariables have a
default value of nil unless otherwise set. Or, since you're getting a
value of 30, something somewhere is saying ZnSignalProgress value: 30
during: ["something"]... which would be very weird.

Thanks!

Hi Frank and Sean. The problem was quite hard to reproduce. You need to
rebuild a Pharo image from a kernel using Tanker ;)
Anyway, since we are changing completely Tanker now it may have been
solved. I did a quick test (of a similar case) and it works. So once I have
the example of the kernel again I will trying again.
Thanks for offering the help!

Mariano, would you give some more details about the wrong value, the
expected value, and the steps to reproduce? I took a look but I'm not
seeing
what the problem is... b.t.w. is this a 1.4 or 2.0 image?
