It's well known, that zip19x32 uses lot of memory and therefore swapspace.
Switch to (2=32 bit) which solves this problem.

1. Info-ZIP "unzip *.zip" (was: Re: OS/2 QWK reader ...)

No, the wildcard-handling feature will be in 5.1.  We actually have
two unofficial (and non-portable) patches which add wildcards to
unzip (one for MS-DOS/Borland C and one for OS/2, the executables of
which were uploaded to ftp-os2 last week; I don't know if it's still
there or not, but it wasn't any sort of official release).  But the
portable way to do this is with readdir-type routines, and I'm still
working on that.  There are a number of other important and *big*
modifications going on right now, so it will be a while before this
even shows up for beta testing.

Follow-ups (if any) to c.o.os2.apps, or you will die a horrible death...
