There seems to be a race condition causing an intermittent failure initializing a remote
compiler collection with an existing userdir.

To duplicate:
1. Remove your userdir
2. Run the IDE and define a remote host and do some action (build or debug).
3. Exit the IDE and restart.

At this point I get a botched compiler collection about 25% of the time. If you open
the T->O panel and select the remote host, it shows 0 compiler sets. If I run with
"-J-Dcnd.remote.logger=FINE" I see the CompilerSetManager.initRemoteCompilerSets()
has been called twice for and that there was an IOException in CompilerSetScriptManager.runScript().

At this point, the remove host is unusable (although I can remove the node and
re-add it).

Here is the cnd.remote.logger output (from messages.log):

Whenever initRemoveCompilerSets is called twice, I get this exception and the CSM
doesn't get initialized.
