23# DESCRIPTION:
24# Verify ZEDLETs only inherit the fds specified in the manpage
25#
26# STRATEGY:
27# 1. Inject a ZEDLET that dumps the fds it gets to a file.
28# 2. Generate some events.
29# 3. Read back the generated files and assert that there is no fd past 3,
30#    and there are exactly 4 fds.
