Thank you for your report.

You didn't show any crashes.  Please do (with meaningful backtraces).

Which version of Cygwin is that?  We had in the past reports about
various problems in specific versions; please try to search the
archives of this list and of emacs-devel, and see if your crashes
resemble some reported in the past.

Please report the numbers: the memory usage figures reported by the
Task Manager before, during, and after the image buffer is killed.

I don't think Emacs returns the memory to the OS immediately, but GC
should cause that.
