I don’t see the same restriction in my Solaris man page ☺
The restriction claim is valid only in the Linux universe. But in a parallel
universe, somebody can make a utility with the same name doing exactly the same
thing.

That's strange. Here is what I have in the man page:
PSTACK(1) Linux Programmer's Manual PSTACK(1)
NAME
pstack - print a stack trace of running processes
SYNOPSIS
pstack pid [...]
DESCRIPTION
pstack attaches to the active processes named by the pids on the com‐
mand line, and prints out an execution stack trace, including a hint at
what the function arguments are. If symbols exist in the binary (usu‐
ally the case unless you have run strip(1)), then symbolic addresses
are printed as well.
If the process is part of a thread group, then pstack will print out a
stack trace for each of the threads in the group.
RESTRICTIONS
pstack currently works only on Linux, only on an x86 machine running 32
bit ELF binaries (64 bit not supported). Also, for symbolic informa‐
tion, you need to use a GNU compiler to generate your program, and you
can't strip symbols from the binaries. For thread information to be
dumped, you have to use the debug-aware version of the LinuxThreads
libpthread.so library. (To check, run nm(1) on your pthreads library,
and make sure that the symbol "__pthread_threads_debug" is defined.)
Threads are not supported with the newer NPTL libpthread.so library.
SEE ALSO
nm(1), ptrace(2)

Apparently, the man page doesn't tell the truth, the whole truth and nothing
but the truth, as it is supposed to do. My confidence in the world just took a
hard blow. What kind of the world do we live in, when one cannot believe the
man pages? BTW, the man page was created in 2002, few weeks ago.
Happy Thanksgiving or what's left of it, with the latest restrictions.

It's Solaris x64 11.4.
Support filed the bug: 31716314 : poll/nanosleep waits weeks when passed 0.01
second timer values passed.
The fix should be included in the next SRU (SRU27) which should be out any
minute.
