I think I know what is the reason for the 3 blank pages: abstract is 
based on chapter* (with asterisk, unnumbered chapter), which inside has 
chapter-unnumbered-title, which in turn is based on chapter-title, which 
has a new-dpage*, which adds a double blank page.

The way to remove the double blank page is therefore to remove the 
new-dpage*.

I have written the following preamble, which is giving me an abstract 
with only one blank page between it and the title. Do copy and then 
Paste from -> TeXmacs to put it in your preamble.


    <assign|render-abstract|<\macro|body>
<surround|<no-indent>||<abstract-chapter*|<abstract-text>>>

      <surround||<hflush>|<arg|body>>
    </macro>>

<assign|abstract-chapter*|<macro|title|<assign|chapter-numbered|false><assign|chapter-prefix|<macro|>><compound|chapter-clean><compound|chapter-header|<arg|title>><compound|chapter-toc|<arg|title>><compound|abstract-unnumbered-title|<arg|title>>>>

<assign|abstract-title|<macro|name|<no-indent><new-line><no-indent><vspace*|5fn><with|math-font-series|bold|font-series|bold|<really-huge|<arg|name>>><vspace|2fn><no-page-break><no-indent*>>>

<assign|abstract-unnumbered-title|<macro|title|<compound|abstract-title|<arg|title><compound|chapter-post-sep>>>>


Said this, there is one thing that I do not understand in this code and 
it may be important, and that is why it uses the compound macro (e.g. 
<compound|chapter-header|<arg|title>>). I wrote the code substituting my 
definitions for definitions that were already there, and leaving the 
compound macro if it was wrapping something that I changed. For example 
<compound|abstract-unnumbered-title|<arg|title>> in the definition of 
abstract-chapter* was <compound|chapter-unnumbered-title|<arg|title>>in 
the definition of chapter* (on which render-abstract is based on).

I do not know if what I did is right or wrong, and I do not know how to 
reason about it. Maybe someone else can explain/correct/improve.
