Changeset 35558 in vbox for trunk/src/VBox/Runtime/r3/posix

Timestamp:

69442

Message:

Runtime/process: add a Solaris-specific flag to suppress changing the contract id (not used at the moment), and put a note in the runtime that the webservice self-daemonizing code relies on the fact that RTProcDaemonizeUsingFork keeps the contract id unchanged, in case someone cleans this up
