I have found the problem.  It was a bug on my side that stemmed from 
my failure to correctly understand the documentation for 
t_lookup_request().  I believe it is written in an ambiguous way, even 
though the mistake is surely mine.

The docs say:

    Checks if a transaction exists. Returns a positive value if so,
    negative otherwise. Most likely you will not want to use it, as a
    typical application of a look-up is to introduce a new transaction
    if none was found. However this is safely (atomically) done using
    t_newtran."

To me, this contains the implicit suggestion that a transaction will 
be created by calling t_lookup_request() if it does not already exist. 
  I was in fact quite mistaken in this and took some measures that 
resulted in bizarre outcomes.

Thanks for your help!
