I've redone testings with the OP's original code, i.e.

    {
      \time 4/4
      \repeat unfold 1000 { c4 d e f } % TEN PAGES of music
      \repeat unfold 1000 { f1 } % + SIX MORE PAGES of music
      \repeat unfold 1000 { c4 d e f } % BUT WHEN ADDING MORE PAGES, fail NOW
    }

Using 2.19.82 (from the installer) and 2.21.0 out of 915799cad7
musicexp.py: Use python 2.4 syntax.

Always restarting the computer after each test.

For 2.19.82 it's finished after 28m4,740s
For 2.21.0 after 24m50,214s

Memory-usage seems to be similar.
I didn't oberve a difference in the final pdfs
