I'm glad my idea worked.

Btw, on a more general note: I presume that your code has a way to
disable threading in file I/O.  (If it doesn't, it should IMO, for
debugging purposes and also for situations where threading cannot be
allowed for some other reasons.)  Then you could simply arrange for
threading to be disabled during dumping, and enable it in startup.el
when Emacs starts normally.  And when threading is disabled, there
should be no need to have any mutex variables.
