Bash problems, strace, performance, etc.

["Lee D. Rothstein" <l1ee057 at veritech dot com>]

 I'm confused. Something is wrong with my Cygwin configuration
that has slowed Cygwin operation down drastically. The
performance issue follows several problems with 'bash' that
occurred while running nested scripts. The residual effect is
slow performance. I've tried 'rebaseall', and that too failed
(although frankly, I've never understood when that's called for
or what it fixes, except in the most abstract of senses.). (See
attached 'Rebaseall_Out.txt.)

The "Bash problem" generates a complaint and a stack trace. The
complaint is:

C:\_0\bin\bash.exe: *** fatal error - WFSO timed out after longjmp

The stack traces are listed in the attached file --
Bash_Problem_Output.txt

The highest level script that generated the problem was
'mkperlmanpdfs' (attached). 'mkperlmanpdfs', in turn, invokes
'man2pdf' (attached) repeatedly.

During several of the 'man2pdf' invocations, errors
are reported by 'man'/'groff' in rendering the 'man' "page" to
Postscript. I've learned to live with these, and only rarely do
they actually lead to omissions in the eventual PDF file. No big
deal. In at least two of the cases, however, Bash itself seems to
be reporting an error.

I've tried shutting down all Cygwin/'mintty' windows, and killing
all residual Cygwin processes/apps, using Task Manager. No help,
whatsoever. I tried rebooting. That did help.

I've also attached Cygcheck output. (The 'cygcheck' follows the
reboot.)
