That would also mean that one couldn't use "IndexedIdentifier", 
"IndexedString", and all such duchain types statically, which would be a 
significant limitation for such cosmetic reasons.

You can always debug the kdevelop startup doing:
KDEV_SESSION_ID=... gdb kdevelop
(gdb) run

with the KDEV_SESSION_ID value read from "ls ~/.kdevduchain" or from the 
debug-output that kdevelop gives on every startup. And you would _only_ need 
that when debugging duchain-directory specific startup problems, for other 
cases we could have a simple "--nofork" option. Btw, startup problems that are 
specific to one duchain repository are very hard to debug anyway, as the whole 
repository is wiped automatically after 2 crashes.
