I had time to look more carefully at the source code in pdftex.web.  It
works by producing a stream of 28-bit integers (details don't matter
here) and rescaling that to the user's requested interval.  This means
for instance that \pdfuniformdeviate 536870912 only produces even
numbers.  This seemingly innocuous loop loops forever.

\loop\ifodd\pdfuniformdeviate 536870912\relax\else\repeat

I don't think XeTeX should adopt this bug for the sake of compatibility.
 I will not have time to implement anything in Pascal nor C in the near
future.

Best regards,

Bruno

Some years ago, Apostolos Syropoulos modified the changebar.sty file 
that comes with the TeXLive distro so that it would work with xelatex, 
by adding
    \DeclareOption{xetex}{\cb at xetexcheck}
etc.

This code seems to be working, but it never got into the TeXLive distro. 
  Should(n't) it?

It should be sent to the maintainer of the package. TeX Live just gets what
is on CTAN. And if it is on CTAN, it will go not only to TeX Live but also
to MikTeX.

Well it was sent to the maintainer (I think I know how things work
since I have uploaded a few packages) but for some reason he
felt that it was not compatible with pdfTeX (I really do not
remember why and I have deleted the emails long time ago). 

Since people think it is useful, I will rename the package into
xechangebar and I will upload it to CTAN ASAP.

May I ask if, since this discussion last took place (September 2016) there has been any progress in resolving the underlying problem ?  If not, is there any possibility of integrating the necessary code into the TeX Live manager such that one can reliably refresh the font cache using the TLMGR GUI rather than through a CMD prompt ?

There has been no progress in that.
I think that probably a cache file to be renamed is not closed
when requested from the XeTeX itself, thus it cannot
be renamed on Windows.

Best,
