[gentoo-user] emerge asynchronous anomoly

[n952162]

Hallo,

there's probably an explanation ...

I'm emerging at this point:

 >>> Emerging (51 of 93) perl-core/Encode-3.120.0::gentoo

and there's NO additional log output for a very long time. Looking at
ps(1) shows this:

http://distfiles.gentoo.org/distfiles/d6/*firefox-78.14.0esr.source.tar.xz*

i.e. it's downloading a tarball for firefox.  But firefox doesn't come
for a few more hours:

 >>> Emerging (52 of 93) virtual/perl-Encode-3.120.0::gentoo
 >>> Emerging (53 of 93) sys-devel/binutils-2.37_p1::gentoo
 >>> Emerging (54 of 93) net-misc/iputils-20210722::gentoo
 >>> Emerging (55 of 93) sys-apps/diffutils-3.8::gentoo
 >>> Emerging (56 of 93) dev-lang/tcl-8.6.11::gentoo
 >>> Emerging (57 of 93) app-emulation/qemu-6.0.0-r3::gentoo

Is it so on top of things that  it's downloading many packages early,
and the download is so aggressive, that nothing else can run?
