> The RamCacheCLFUSCompressor is scheduled in the new_RamCacheCLFUS function instead of the init. If Vol init (and subsequently RamCacheCLFUS::init) takes too long the compressor may run before a vol is assigned to the RamCache and causes a segfault.
> I was able to reproduce this with --enable-debug and 18 volumes. This delayed the RamCache init long enough for this to hit.
> This may be the cause of TS-1612 as well, but it isn't clear from that bug report.
