sorry if i said this not clearly.

Not all threads are waiting only the one which does the astdb call.

for example sip channel:
a register msg is received
asterisk does its checks of secret, acl and so on
then call astdb_put to write the data into the astdb (have a look at
"database show" you will see sip peer register contacts in there)
in astdb_put the astdb->sync function is called to ensure data is really
saved to disk which take some time.
until astdb->sync is finished no other sip package is read, or schedule
is launched.
