What is sigcleanup?

In the process of debugging a perl program, I used "trace"
and noticed that "trace" repeatedly showed calls to 
"sigcleanup" (which occasionally looped).

Searching for "sigcleanup" in perl and C libraries 
(and manual pages as well) did not give any explanation 
of "sigcleanup", except that:

1) entry #139 in /usr/include/sys/syscall.h is unused.
2) "strings /usr/bin/trace" shows sigcleanup as placed 
   between "utimes" and "adjtime" (#138 and #140 respectively).

What is "sigcleanup" doing?

We use sun3, SunOS 4.0.3, perl 3.44.
