Locks are not shared with the nsd process. The libnsd library came about as a result of folks wanting some of the AOLserver core Tcl APIs from within stand alone tclsh processes.
You might also want to look at the new nsproxy module. That code allows you to start a pool of tclsh processes that you can send commands to. It's a great way to deal with code which is not thread safe, since each tclsh, by default, is single threaded. The tclsh processes are fork'd and exec'd from the main nsd process.
Example:
ns_proxy pool
-----------------
nsd (MT) <----> tclsh (ST)
<----> tclsh (ST)
<----> tclsh (ST)
- n

Subject: [AOLSERVER] question about libnsd loading in tclsh
In the 4.5 release docs, it was announced:
libnsd:
The AOLserver library now includes an entry point suitable
for loading into an ordinary, thread-enabled, tclsh, e.g.,:
# tclsh
% load /usr/local/aolserver/lib/libnsd.so
% ns_time
Does this loaded libnsd.so share locks, such as ndb_handles and semaphores with an already running nsd?
I assume not, but thought I'd ask...
What I'm trying to do is run command-line tcl commands that would access my berkeleydb database while aolserver is still running, and if two separate processes are writing the same db file, it gets corrupted.
