Richard,
If a quick workaround is fitting, the problem can be dodged at the system
level. I'll pick 8192 open files on Linux for example:
/etc/security/limits.conf
myuser hard nofile 8192
myuser soft nofile 8192
This doesn't address the open file count within Raku, but sometimes people just
want to get by the snag and keep flowing.

Subject: too many file handles
I have been running into this error: "Too many open files"
Sorry for the lack of detail. The problem is that the error comes up in odd
places, so I have found it difficult to golf down into Raku program that always
fails with this error.
When I separate out the code that leads to the error, and create another
program, Raku handles it without difficulty. It seems to occur when there are a
lot of moving parts, so to speak.
I am not explicitly opening file handles, but the software I have written is
using the idiom
"some-filename.html".IO.spurt( $an-accumulated-string );
Obviously, filehandles are being opened under the hood. Having written a file,
there is no need to reference it again, so I could close the filehandle.
I have been told that because of the way garbage handling is implemented, there
is a problem with file handles. If so, what is a safer idiom to use in place of
and IO on a string, so that the handle can be closed immediately after use?
Appreciate some help on this.
Richard
