killing gem/topaz while doing index removal can crash reclaim GcGems

Killing a gem/topaz session while it is doing an index removal operation includes a possible risk of a reclaim GcGem crashing with a page cache fault.

Index removal operations include:
    #removeAllIndexes
    #removeEqualityIndexOn:
    #removeIdentityIndexOn:

The crashed reclaim GcGem logs will contain entries like:

*************** Page Cache Fault ***************
  occurred at /some-file-directory-structure/pagecache.hc: NN
  message is: Page header fault on page NN, expected kind 7, found kind NN

(Where NN indicates numbers)
