Keith,
in addition to Elliot's comment, you can use

   rebase -si

output to  provide an overview of how many dll's are present
and in which address they are mapped.

   $ rebase -si |sort -r --key=5 | head

will provide the list of the one absorbing more address space.
Except the octave-tisean patological case, that I recommend to not 
install if you don't really need it, usually LLVM and ICU
several DLL's are the largest:

  $ rebase -si |sort -r --key=5 | head |awk '{print $5,$1}'
0x020b3000 /usr/bin/cygLLVM-4.0.dll
0x01f75000 /usr/bin/cygQt5WebKit-5.dll
0x01def000 /usr/bin/cygLLVM-3.9.dll
0x01af3000 /usr/bin/cygLLVM-3.8.dll
0x0191d000 /usr/bin/cygicudata59.dll
0x0190a000 /usr/bin/cygicudata58.dll
0x01885000 /usr/bin/cygicudata57.dll
0x017ed000 /usr/bin/cygicudata56.dll
0x01239000 /usr/bin/cyggcj-16.dll
0x00f4f000 /usr/bin/cygoctave-4.dll
