Random crash while running ekam -c

[jparyani]

The following happened randomly while I was doing a bunch of git rebase commands in the sandstorm directory while running make continuous

install: sandstorm/sandstorm.ekam-manifest
terminate called after throwing an instance of 'ekam::OsError'
  what():  inotify_rm_watch(inotify): Invalid argument
Aborted
Makefile:139: recipe for target 'continuous' failed
make: *** [continuous] Error 134

Yeah, inotify is notoriously difficult, so ekam sometimes barfs when a lot of stuff changes at once.

At some point I want to rewrite things to be in terms of KJ primitives, and add an inotify primitive to KJ with a sane interface, after which these issues should be gone. In the meantime it doesn't happen too often in my experience...
